## Data

# Struct Data

Source

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

Expand description

A container that allows easily replacing chunks of its data.

## Fields§

§`original: Vec<u8>`

Original data.

§`parts: Vec<Span>`

`Span`s 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§

Source§

### impl Data

Source

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

Create a new data container from a slice of bytes

Source

#### pub fn commit(&mut self)

Commit the current changes.

Source

#### pub fn restore(&mut self)

Discard uncommitted changes.

Source

#### 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.

Source

#### 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.

## 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.
