Struct Data

pub struct Data {
    original: Vec<u8>,
    parts: Vec<Span>,
}

A container that allows easily replacing chunks of its data.

Fields

original: Vec<u8>

Original data.

parts: Vec<Span>

Spans covering the full range of the original data. Important: it’s expected that the underlying implementation maintains this in order, sorted ascending by start position.

Implementations

impl Data

pub fn new(data: &[u8]) -> Self

Create a new data container from a slice of bytes

pub fn commit(&mut self)

Commit the current changes.

pub fn restore(&mut self)

Discard uncommitted changes.

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

Merge the original data with changes, including uncommitted changes.

See the module-level documentation for more information on why uncommitted changes are included.

pub fn replace_range( &mut self, range: Range<usize>, data: &[u8], ) -> Result<(), Error>

Record a provisional change.

If committed, the original data in the given range will be replaced by the given data. If there already exist changes for data in the given range (committed or not), this method will return an error. It will also return an error if the beginning of the range comes before its end, or if the range is outside that of the original data.

Trait Implementations

impl Clone for Data

fn clone(&self) -> Data

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Data

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

Formats the value using the given formatter.

impl Default for Data

fn default() -> Data

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
