Expand description

Handle for sequential, chunk-cached reads of one file.

Implementations§

Source§

impl<'a, F: Flash, M: RawMutex, const MAX_PATH_LEN: usize, const CHUNK_SIZE: usize> EkvFile<'a, F, M, MAX_PATH_LEN, CHUNK_SIZE>

Source

pub const fn meta(&self) -> &FileMeta

File metadata (size and chunk count).

Source

pub const fn size(&self) -> usize

Total file size in bytes.

Source

pub async fn read(&mut self, buf: &mut [u8]) -> Result<usize, Error>

Reads up to buf.len() bytes, advancing an internal offset.

Returns 0 at end-of-file.
