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