Returns a copy of the value. Read more
1.0.0 · source§

fn clone_from(&mut self, source: &Self)

source§

impl DynTagged for Length

source§

fn tag(&self) -> Tag

source§

impl From<usize> for Length

source§

fn from(l: usize) -> Self

Converts to this type from the input type.
source§

impl PartialEq for Length

source§

fn eq(&self, other: &Length) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
source§

impl ToDer for Length

source§

fn to_der_len(&self) -> Result<usize>

Get the length of the object (including the header), when encoded
source§

fn write_der_header(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER header to this writer.
source§

fn write_der_content(&self, _writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER content (all except header) to this writer.
source§

fn to_der_vec(&self) -> SerializeResult<Vec<u8>>

Write the DER encoded representation to a newly allocated Vec<u8>.
source§

fn to_der_vec_raw(&self) -> SerializeResult<Vec<u8>>

Similar to using to_vec, but uses provided values without changes. This can generate an invalid encoding for a DER object.

source§

fn write_der_raw(&self, writer: &mut dyn Write) -> SerializeResult<usize>
