Struct BlockLocation 

pub struct BlockLocation {
    pub offset: u64,
    pub size: usize,
}

A block that can be read or written in a crate::FileReader or crate::FileWriter.

Fields

offset: u64

Byte offset, a multiple of 512.

size: usize

Size in bytes, a multiple of 512, less than 2**31.

(The upper limit is because some kernel APIs return the number of bytes read as an i32.)

Implementations

impl BlockLocation

pub fn new(offset: u64, size: usize) -> Result<Self, InvalidBlockLocation>

Constructs a new BlockLocation, validating offset and size.

pub fn after(&self) -> u64

File offset just after this block.

Trait Implementations
