Struct ProbeCachedDataSource 

pub struct ProbeCachedDataSource<'a> { /* private fields */ }

Small-window cache for repeated probe reads near the start of a source.

Implementations

impl<'a> ProbeCachedDataSource<'a>

pub fn new(inner: &'a dyn ByteSource) -> Self

Wrap a source with a probe-oriented cache.

Trait Implementations

impl ByteSource for ProbeCachedDataSource<'_>

fn read_at(&self, offset: u64, buf: &mut [u8]) -> Result<usize>

Read bytes starting at offset into buf.

fn size(&self) -> Result<u64>

Return the total size of this source in bytes.

fn capabilities(&self) -> ByteSourceCapabilities

Describe the backend’s read behavior.

fn telemetry_name(&self) -> &'static str

Return a stable label for tracing and diagnostics.

fn read_exact_at(&self, offset: u64, buf: &mut [u8]) -> Result<()>

Read exactly buf.len() bytes from offset.

fn read_bytes_at(&self, offset: u64, len: usize) -> Result<Vec<u8>>

Read len bytes from offset into a new buffer.

fn read_all(&self) -> Result<Vec<u8>>

Materialize the full source into memory.
