Struct LiquidityTier 

pub struct LiquidityTier {
    pub id: u32,
    pub name: String,
    pub initial_margin_ppm: u32,
    pub maintenance_fraction_ppm: u32,
    pub base_position_notional: u64,

}

LiquidityTier stores margin information.

Fields

id: u32

Unique id.

name: String

The name of the tier purely for mnemonic purposes, e.g. “Gold”.

initial_margin_ppm: u32

The margin fraction needed to open a position. In parts-per-million.

maintenance_fraction_ppm: u32

The fraction of the initial-margin that the maintenance-margin is, e.g. 50%. In parts-per-million.

base_position_notional: u64

👎Deprecated

The maximum position size at which the margin requirements are not increased over the default values. Above this position size, the margin requirements increase at a rate of sqrt(size).

Deprecated since v3.x.

impact_notional: u64

The impact notional amount (in quote quantums) is used to determine impact bid/ask prices and its recommended value is 500 USDC / initial margin fraction.

• Impact bid price = average execution price for a market sell of the impact notional value.
• Impact ask price = average execution price for a market buy of the impact notional value.

open_interest_lower_cap: u64

Lower cap for Open Interest Margin Fracton (OIMF), in quote quantums. IMF is not affected when OI <= open_interest_lower_cap.

open_interest_upper_cap: u64

Upper cap for Open Interest Margin Fracton (OIMF), in quote quantums. IMF scales linearly to 100% as OI approaches open_interest_upper_cap. If zero, then the IMF does not scale with OI.

Trait Implementations

impl Clone for LiquidityTier

fn clone(&self) -> LiquidityTier

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LiquidityTier

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for LiquidityTier

fn default() -> LiquidityTier

Returns the “default value” for a type.

impl Message for LiquidityTier

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl Name for LiquidityTier

const NAME: &'static str = "LiquidityTier"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "dydxprotocol.perpetuals"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for LiquidityTier

fn eq(&self, other: &LiquidityTier) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
