Expand description
Defines how to deserialize Self
from bytes.
Required Methods
sourcefn read_from<R: ByteReader>(
source: &mut R
) -> Result<Self, DeserializationError>
fn read_from<R: ByteReader>(
source: &mut R
) -> Result<Self, DeserializationError>
Reads a sequence of bytes from the provided source
, attempts to deserialize these bytes
into Self
, and returns the result.
Errors
Returns an error if:
- The
source
does not contain enough bytes to deserializeSelf
. - Bytes read from the
source
do not represent a valid value forSelf
.
Provided Methods
sourcefn read_batch_from<R: ByteReader>(
source: &mut R,
num_elements: usize
) -> Result<Vec<Self>, DeserializationError>
fn read_batch_from<R: ByteReader>(
source: &mut R,
num_elements: usize
) -> Result<Vec<Self>, DeserializationError>
Reads a sequence of bytes from the provided source
, attempts to deserialize these bytes
into a vector with the specified number of Self
elements, and returns the result.
Errors
Returns an error if:
- The
source
does not contain enough bytes to deserialize the specified number of elements. - Bytes read from the
source
do not represent a valid value forSelf
for any of the elements.
Note: if the error occurs, the reader is not rolled back to the state prior to calling this function.
