Struct RegistryClient 

pub struct RegistryClient { /* private fields */ }

Implementations

impl RegistryClient

pub fn new(registry: Registry) -> Result<Self>

pub fn with_cache_dir(self, cache_dir: PathBuf) -> Self

Set the cache directory for sparse index fragments

pub fn registry(&self) -> &Registry

pub fn version_exists(&self, crate_name: &str, version: &str) -> Result<bool>

pub fn crate_exists(&self, crate_name: &str) -> Result<bool>

pub fn list_owners( &self, crate_name: &str, token: &str, ) -> Result<OwnersResponse>

pub fn check_new_crate(&self, crate_name: &str) -> Result<bool>

Check if a crate is new (doesn’t exist in the registry).

Returns true if the crate doesn’t exist, false if it does.

pub fn check_index_visibility( &self, crate_name: &str, version: &str, ) -> Result<bool>

Check if a crate version is visible via the sparse index.

Returns true if the version is found in the index, false otherwise. Parse errors and network errors are treated as “not visible” rather than failures.

pub fn verify_ownership(&self, crate_name: &str, token: &str) -> Result<bool>

Attempt ownership verification for a crate.

Returns true if ownership is verified, false if verification fails or endpoint is unavailable. This function implements graceful degradation - if the ownership check fails due to API limitations, it returns false rather than an error.

pub fn is_version_visible_with_backoff( &self, crate_name: &str, version: &str, config: &ReadinessConfig, ) -> Result<(bool, Vec<ReadinessEvidence>)>

Check if a version is visible with exponential backoff and jitter.

Returns Ok((true, evidence)) if the version becomes visible within the timeout, Ok((false, evidence)) if the timeout is exceeded, or Err on other failures.

pub fn calculate_backoff_delay( &self, base: Duration, max: Duration, attempt: u32, jitter_factor: f64, ) -> Duration

Calculate the backoff delay for a given attempt with jitter.

This is a helper function that can be used for testing.
