Struct asn1::Parser

pub struct Parser<'a> { /* fields omitted */ }

Encapsulates an ongoing parse. For almost all use-cases the correct entry-point is parse or parse_single.

Implementations

impl<'a> Parser<'a>

pub fn is_empty(&self) -> bool

Tests whether there is any data remaining in the Parser. Generally useful when parsing a SEQUENCE OF.

pub fn read_element<T: Asn1Readable<'a>>(&mut self) -> ParseResult<T>

Reads a single ASN.1 element from the parser. Which type you are reading is determined by the type parameter T.

pub fn read_explicit_element<T: Asn1Readable<'a>>(
    &mut self,
    tag: u8
) -> ParseResult<T>

This is an alias for read_element::<Explicit<T, tag>> for use when MSRV is < 1.51.

pub fn read_optional_explicit_element<T: Asn1Readable<'a>>(
    &mut self,
    tag: u8
) -> ParseResult<Option<T>>

This is an alias for read_element::<Option<Explicit<T, tag>>> for use when MSRV is <1.51.

pub fn read_implicit_element<T: SimpleAsn1Readable<'a>>(
    &mut self,
    tag: u8
) -> ParseResult<T>

This is an alias for read_element::<Implicit<T, tag>> for use when MSRV is <1.51.

pub fn read_optional_implicit_element<T: SimpleAsn1Readable<'a>>(
    &mut self,
    tag: u8
) -> ParseResult<Option<T>>

This is an alias for read_element::<Option<Implicit<T, tag>>> for use when MSRV is <1.51.
