Enum Tier 

pub enum Tier {
    Standard,
    Copper,
    Bronze,
    Silver,
    Gold,
    Platinum,
    Diamond,
    Elite,
}

An account’s volume tier, which sets both buckets’ rate and capacity.

Tier is assigned upstream from 30-day volume. Clients cannot compute it, so it is discovered from the Poly-RateLimit-Tier response header; until one is seen, Tier::Standard is assumed because it is the tightest.

Variants

Standard

No volume requirement.

Copper

$30,000+ 30-day volume.

Bronze

$50,000+ 30-day volume.

Silver

$100,000+ 30-day volume.

Gold

$500,000+ 30-day volume.

Platinum

$2.5M+ 30-day volume.

Diamond

$5M+ 30-day volume.

Elite

$10M+ 30-day volume.

Implementations

impl Tier

pub fn rate(self, bucket: TradingBucket) -> u32

Sustained refill rate for bucket, in tokens per second.

pub fn burst(self, bucket: TradingBucket) -> u32

Burst capacity for bucket — the most tokens it ever holds.

A request costing more than this can never be satisfied, however long the caller waits.

pub fn from_header(value: &str) -> Option<Self>

Parse the value of a Poly-RateLimit-Tier header.

Matching is case-insensitive; an unrecognised tier returns None rather than guessing, so an upstream addition cannot silently widen a bucket.

Trait Implementations

impl Clone for Tier

fn clone(&self) -> Tier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Tier

impl Debug for Tier

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

Formats the value using the given formatter.

impl Default for Tier

fn default() -> Tier

Returns the “default value” for a type.

impl Eq for Tier

impl Ord for Tier

fn cmp(&self, other: &Tier) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Tier

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Tier

fn partial_cmp(&self, other: &Tier) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
