pub struct DetectReader { /* private fields */ }
Expand description
The BufRead
type reads from compressed or uncompressed file.
This reader detects compression algorithms from file name extension.
Implementations§
Source§impl DetectReader
impl DetectReader
Sourcepub fn open<P: AsRef<Path>>(path: P) -> Result<DetectReader>
pub fn open<P: AsRef<Path>>(path: P) -> Result<DetectReader>
Open compressed or uncompressed file.
Sourcepub fn open_with_wrapper<P: AsRef<Path>, B: ReadWrapperBuilder>(
path: P,
builder: B,
) -> Result<DetectReader>
pub fn open_with_wrapper<P: AsRef<Path>, B: ReadWrapperBuilder>( path: P, builder: B, ) -> Result<DetectReader>
Open compressed or uncompressed file using wrapper type.
InnerReadWrapper
is the wrapepr type’s trait handles compressed byte stream.
For example, the progress-counting wrapper enables you to calculate progress of loading.
