Trait AlignedFileReader 

Source 
pub trait AlignedFileReader: Send + Sync {
    type Alignment: Alignment;

    // Required method
    fn read(
        &mut self,
        read_requests: &mut [AlignedRead<'_, u8, Self::Alignment>],
    ) -> ANNResult<()>;
}

Required Associated Types§

Source

type Alignment: Alignment

Alignment requirement applied to every AlignedRead<u8, Self::Alignment> passed to Self::read. All three constraints — buffer pointer, buffer length, and disk offset — are checked against this value at AlignedRead::new time.

Direct-I/O readers (O_DIRECT, FILE_FLAG_NO_BUFFERING) set this to the device sector size (typically 512 bytes); buffered readers use A1. The caller is responsible for generating offsets and buffers that satisfy this alignment — DiskSectorGraph, for example, requires its block_size to be a multiple of Self::Alignment::VALUE.

Required Methods§

Source

fn read( &mut self, read_requests: &mut [AlignedRead<'_, u8, Self::Alignment>], ) -> ANNResult<()>

Read the data from the file by sending concurrent io requests in batches.

Dyn Compatibility§

This trait is dyn compatible.

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