Struct ethers::core::k256::elliptic_curve::pkcs8::der::asn1::ContextSpecific

pub struct ContextSpecific<'a> {
    pub tag_number: TagNumber,
    pub value: Any<'a>,
}

Context-specific field.

This type encodes a field which is specific to a particular context, and is identified by a TagNumber.

Any context-specific field can be decoded/encoded with this type. The intended use is to dynamically dispatch off of the context-specific tag number when decoding, which allows support for extensions, which are denoted in an ASN.1 schema using the ... ellipsis extension marker.

Fields

tag_number: TagNumber

Context-specific tag number sans the leading 0b10000000 class identifier bit and 0b100000 constructed flag.

value: Any<'a>

Value of the field.

impl<'a> Debug for ContextSpecific<'a>

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a> Encodable for ContextSpecific<'a>

pub fn encoded_len(&self) -> Result<Length, Error>

Compute the length of this value in bytes when encoded as ASN.1 DER.

pub fn encode(&self, encoder: &mut Encoder<'_>) -> Result<(), Error>
