Implementations§
source§impl ConverterInputStream
impl ConverterInputStream
pub const NONE: Option<&'static ConverterInputStream> = None
sourcepub fn new(
base_stream: &impl IsA<InputStream>,
converter: &impl IsA<Converter>
) -> ConverterInputStream
pub fn new( base_stream: &impl IsA<InputStream>, converter: &impl IsA<Converter> ) -> ConverterInputStream
Creates a new converter input stream for the base_stream
.
base_stream
converter
Returns
a new InputStream
.
sourcepub fn builder() -> ConverterInputStreamBuilder
pub fn builder() -> ConverterInputStreamBuilder
Creates a new builder-pattern struct instance to construct ConverterInputStream
objects.
This method returns an instance of ConverterInputStreamBuilder
which can be used to create ConverterInputStream
objects.
