Expand description
This structure implements io::BufRead
and represents
the payload of a TransactionPayloadEvent
.
Implementations§
source§impl<'a> TransactionPayloadReader<'a>
impl<'a> TransactionPayloadReader<'a>
sourcepub fn new_uncompressed(data: &'a [u8]) -> Self
pub fn new_uncompressed(data: &'a [u8]) -> Self
Creates new instance (data
is not compressed).
sourcepub fn new_zstd(data: &'a [u8]) -> Result<Self>
pub fn new_zstd(data: &'a [u8]) -> Result<Self>
Creates new instance (data
is ZSTD-compressed).
sourcepub fn has_data_left(&mut self) -> Result<bool>
pub fn has_data_left(&mut self) -> Result<bool>
Returns false
if the reader is exhausted.
Some io might be necessary to check for data,
so this functions returns Result<bool>
, not bool
.
