Struct OffsetList

Source
pub struct OffsetList {
    pub zero_prefix: usize,
    pub smol: Vec<u32>,
    pub chonk: Vec<u64>,
}
Expand description

A list of unsigned integers that uses u32 elements as long as they are small enough, and switches to u64 once they are not.

Fields§

§zero_prefix: usize

Length of a prefix of zero elements.

§smol: Vec<u32>

Offsets that fit within a u32.

§chonk: Vec<u64>

Offsets that either do not fit in a u32, or are inserted after some offset that did not fit.

Implementations§

Source§

impl OffsetList

Source

pub fn with_capacity(cap: usize) -> Self

Allocate a new list with a specified capacity.

Source

pub fn push(&mut self, offset: usize)

Inserts the offset, as a u32 if that is still on the table.

Source

pub fn index(&self, index: usize) -> usize

Like std::ops::Index, which we cannot implement as it must return a &usize.

Source

pub fn len(&self) -> usize

The number of offsets in the list.
