Trait SegmentReadAt 

pub trait SegmentReadAt: Send + Sync {
    // Required methods
    fn read_at(&self, buffer: &mut [u8], offset: u64) -> Result<usize>;
    fn len(&self) -> Result<u64>;

    // Provided method
    fn is_empty(&self) -> Result<bool> { ... }
}

A stable-length, thread-safe segment backing with independent positioned reads.

Implementations may return short reads and must never return more than the supplied buffer length. Evidence bytes must remain unchanged while open.

Required Methods

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

Reads bytes at a segment-relative offset without a shared cursor.

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

Returns the backing length.

Provided Methods

fn is_empty(&self) -> Result<bool>

Returns whether the backing is empty.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
