Struct asn1::Writer

pub struct Writer<'a> { /* private fields */ }

Encapsulates an ongoing write. For almost all use-cases the correct entrypoint is write() or write_single().

Implementations

impl Writer<'_>

pub fn write_element<T: Asn1Writable>(&mut self, val: &T) -> WriteResult

Writes a single element to the output.

pub fn write_explicit_element<T: Asn1Writable>( &mut self, val: &T, tag: u32 ) -> WriteResult

This is an alias for write_element::<Explicit<T, tag>>.

pub fn write_optional_explicit_element<T: Asn1Writable>( &mut self, val: &Option<T>, tag: u32 ) -> WriteResult

This is an alias for write_element::<Option<Explicit<T, tag>>>.

pub fn write_implicit_element<T: SimpleAsn1Writable>( &mut self, val: &T, tag: u32 ) -> WriteResult

This is an alias for write_element::<Implicit<T, tag>>.

pub fn write_optional_implicit_element<T: SimpleAsn1Writable>( &mut self, val: &Option<T>, tag: u32 ) -> WriteResult

This is an alias for write_element::<Option<Implicit<T, tag>>>.

pub fn write_tlv<F: FnOnce(&mut WriteBuf) -> WriteResult>( &mut self, tag: Tag, body: F ) -> WriteResult

Writes a TLV with the specified tag where the value is any bytes written to the Vec in the callback. The length portion of the TLV is automatically computed.
