Implementations

impl<'a, T, E> TaggedParser<'a, Explicit, T, E>

pub const fn new_explicit( class: Class, tag: u32, inner: T, ) -> TaggedParser<'a, Explicit, T, E>

pub fn from_ber_and_then<F>( class: Class, tag: u32, bytes: &'a [u8], op: F, ) -> Result<(&'a [u8], T), Err<E>>

where F: FnOnce(&'a [u8]) -> Result<(&'a [u8], T), Err<E>>, E: From<Error>,

Parse a BER tagged value and apply the provided parsing function to content

After parsing, the sequence object and header are discarded.

Note: this function is provided for Explicit, but there is not difference between explicit or implicit tags. The op function is responsible of handling the content.

where F: FnOnce(&'a [u8]) -> Result<(&'a [u8], T), Err<E>>, E: From<Error>,

Parse a DER tagged value and apply the provided parsing function to content

After parsing, the sequence object and header are discarded.
