Struct flatcontainer::impls::offsets::OffsetList

pub struct OffsetList {
    pub smol: Vec<u32>,
    pub chonk: Vec<u64>,
}

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

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

impl OffsetList

pub fn with_capacity(cap: usize) -> Self

Allocate a new list with a specified capacity.

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

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

Panics

Panics if usize does not fit in u64.

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

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

Panics

Panics if the index is out of bounds, i.e., it is larger or equal to the length.

pub fn len(&self) -> usize

The number of offsets in the list.

pub fn is_empty(&self) -> bool

Returns true if this list contains no elements.

pub fn reserve(&mut self, additional: usize)

Reserve space for additional elements.

pub fn clear(&mut self)

Remove all elements.

Trait Implementations

impl Clone for OffsetList

fn clone(&self) -> OffsetList

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OffsetList

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for OffsetList

fn default() -> OffsetList

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OffsetList

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for OffsetList

fn eq(&self, other: &OffsetList) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for OffsetList

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
