A half-open byte range used for a file lock.

Implementations

impl FileLockRange

pub fn new(start: u64, end: Option<u64>) -> Result<Self>

Creates a range from start to the exclusive end, or to EOF.

Returns an error if end precedes start.

pub const fn to_eof(start: u64) -> Self

Creates a range extending from start to EOF.

pub const fn start(self) -> u64

Returns the inclusive starting offset.

pub const fn end(self) -> Option<u64>

Returns the exclusive ending offset, or None for EOF.

pub fn is_empty(self) -> bool

Returns whether this range contains no bytes.
