Struct Reader

pub struct Reader<T> { /* private fields */ }

Struct to read KTX v.2 files.

Implementations

impl<T: AsyncRead + AsyncSeek + Unpin> Reader<T>

Implementation of Reader struct for async loading.

pub async fn new(input: T) -> ReadResult<Self>

Create new instance of Reader.
Asyncroniosly reads and tries to parse data from input.

Errors

If reading fails, returns ReadError::IoError.
If parsing fails, returns ReadError::ParseError.

pub async fn read_data(&mut self) -> ReadResult<Vec<u8>>

Reads data of texture.
Gets vector of bytes. It stores color data of texture. Layout of this data can be obtined from regions_description() method of self.

pub async fn read_data_to(&mut self, buf: &mut [u8]) -> ReadToResult<()>

Reads data of texture.

Reads texture data to buf. Layout of this data can be obtined from regions_description() method of self.
Size of buf MUST be equal to expected data size. It can be obtained with data_len_bytes() method.

pub fn header(&self) -> &Header

Returns Header of texture.

pub fn regions_description(&self) -> Vec<RegionDescription>

Returns vector of RegionDescription for texture.

pub fn data_len_bytes(&self) -> u64

Full length of texture data.
