Struct DiagnosticsCache 

pub struct DiagnosticsCache { /* private fields */ }

Bounded per-session LRU cache for diagnostics pushed via lsp/publishDiagnostics.

Holds diagnostics for at most max_files files. When a new URI is inserted at capacity, the least-recently-used file is evicted.

URI keys are compared as-is; normalization (case, symlinks) is the IDE’s responsibility.

Examples

use zeph_acp::DiagnosticsCache;

let mut cache = DiagnosticsCache::new(10);
assert!(cache.is_empty());
assert!(cache.peek("file:///src/main.rs").is_none());

Implementations

impl DiagnosticsCache

pub fn new(max_files: usize) -> Self

Create a new cache with the given file limit (minimum 1).

Examples

use zeph_acp::DiagnosticsCache;

let cache = DiagnosticsCache::new(50);
assert!(cache.is_empty());

pub fn update(&mut self, uri: String, diagnostics: Vec<LspDiagnostic>)

Insert or replace diagnostics for a URI, evicting the oldest entry when at capacity.

pub fn peek(&self, uri: &str) -> Option<&[LspDiagnostic]>

Peek at diagnostics for a URI without refreshing LRU order.

Returns None if not cached. Reads do not affect eviction order — only update() refreshes recency. Rename from get() to make peek semantics explicit.

pub fn all_non_empty(&self) -> Vec<(&str, &[LspDiagnostic])>

Return all files that have at least one diagnostic.

pub fn clear(&mut self)

Clear all cached diagnostics.

pub fn len(&self) -> usize

Number of files currently in the cache.

pub fn is_empty(&self) -> bool

Returns true if the cache has no entries.
