Expand description

Struct representing a zTXt chunk

Fields§

§keyword: String

Keyword field of the tEXt chunk. Needs to be between 1-79 bytes when encoded as Latin-1.

Implementations§

source§

impl ZTXtChunk

source

pub fn new(keyword: impl Into<String>, text: impl Into<String>) -> Self

Creates a new ZTXt chunk.

source

pub fn decompress_text(&mut self) -> Result<(), DecodingError>

Decompresses the inner text, mutating its own state. Can only handle decompressed text up to DECOMPRESSION_LIMIT bytes.

source

pub fn decompress_text_with_limit( &mut self, limit: usize ) -> Result<(), DecodingError>

Decompresses the inner text, mutating its own state. Can only handle decompressed text up to limit bytes.

source

pub fn get_text(&self) -> Result<String, DecodingError>

Decompresses the inner text, and returns it as a String. If decompression uses more the 2MiB, first call decompress with limit, and then this method.

source

pub fn compress_text(&mut self) -> Result<(), EncodingError>

Compresses the inner text, mutating its own state.

impl PartialEq<ZTXtChunk> for ZTXtChunk

source§

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

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.
