Struct PoolSnapshot 

pub struct PoolSnapshot {
    pub strings: Vec<String>,
}

A serializable snapshot of a StringPool.

Can be used to persist the pool to disk or transfer it across processes.

Fields

strings: Vec<String>

The interned strings, in index order.

Implementations

impl PoolSnapshot

pub fn len(&self) -> usize

Number of strings in the snapshot.

pub fn is_empty(&self) -> bool

Whether the snapshot is empty.

pub fn get(&self, id: InternedString) -> Option<&str>

Get a string by its interned index.

pub fn restore(&self) -> StringPool

Restore a StringPool from this snapshot.

pub fn total_bytes(&self) -> usize

Total bytes of string data in the snapshot.

pub fn encode(&self) -> Vec<u8>

Encode the snapshot as a single byte vector (length-prefixed strings).

pub fn decode(data: &[u8]) -> Option<Self>

Decode a snapshot from bytes produced by Self::encode.

Trait Implementations

impl Clone for PoolSnapshot

fn clone(&self) -> PoolSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PoolSnapshot

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

Formats the value using the given formatter.

impl PartialEq for PoolSnapshot

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

Tests for self and other values to be equal, and is used by ==.

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

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