Struct ImmutableString

pub struct ImmutableString { /* private fields */ }

Available on crate feature source-tracking only.

An immutable string that either

• References a source string in memory using a 'static reference,
• Owns a source string in memory.
• Owns a locked and memory mapped file from the disk.

This uses an Arc internally to make cloning cheap.

Implementations

impl ImmutableString

pub fn line_starts(&self) -> Vec<usize>

Get a list of byte indices into this ImmutableString of the start of every line.

pub fn as_str(&self) -> &str

Get this ImmutableString as a str reference. This just calls AsRef::as_ref.

pub fn len(&self) -> usize

Get the length of this ImmutableString in bytes. See str::len.

pub fn is_empty(&self) -> bool

Check if this ImmutableString is empty.

Trait Implementations

impl AsRef<str> for ImmutableString

fn as_ref(&self) -> &str

impl Clone for ImmutableString

fn clone(&self) -> ImmutableString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImmutableString

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