ChunkRateLimiter

vta_backup::ops::chunked

Struct ChunkRateLimiter 

Source 
pub struct ChunkRateLimiter { /* private fields */ }
Expand description

Token bucket per authenticated DID for chunk requests.

In-process and deliberately simple: the quantity it protects (disk reads, hashing, bitmap writes on this VTA) is per-process too.

Implementations§

Source§

impl ChunkRateLimiter

Source

pub fn new(per_second: f64, burst: f64) -> Self

Source

pub fn global() -> &'static Self

The process-wide limiter the Trust Task handlers use.

Source

pub fn check(&self, did: &str) -> Result<(), ChunkedError>

Spend one request for did, or say how long until one is available.
