Struct AsnBuilder 

pub struct AsnBuilder { /* private fields */ }

Fluent builder for constructing ASN.1 values.

Example

let data = AsnBuilder::new()
    .sequence(|s| {
        s.integer(42)
         .octet_string(b"hello")
         .boolean(true)
    })
    .build();

Implementations

impl AsnBuilder

pub fn new() -> Self

Create a new empty builder.

pub fn boolean(self, value: bool) -> Self

Add a BOOLEAN value.

pub fn integer(self, value: i64) -> Self

Add an INTEGER value.

pub fn big_integer(self, bytes: &[u8]) -> Self

Add a BigInteger value (raw bytes, two’s complement).

pub fn bit_string(self, data: &[u8], unused_bits: u8) -> Self

Add a BIT STRING value.

pub fn octet_string(self, data: &[u8]) -> Self

Add an OCTET STRING value.

pub fn null(self) -> Self

Add a NULL value.

pub fn oid(self, arcs: &[u32]) -> Self

Add an OBJECT IDENTIFIER value.

pub fn utf8_string(self, s: &str) -> Self

Add a UTF8String value.

pub fn enumerated(self, value: i64) -> Self

Add an ENUMERATED value.

pub fn context_specific(self, number: u8, data: &[u8]) -> Self

Add a context-specific tagged value.

pub fn context_specific_value(self, number: u8, value: &AsnValue) -> Self

Add a context-specific tagged value wrapping an encoded ASN.1 value.

pub fn sequence<F>(self, f: F) -> Self

where F: FnOnce(AsnBuilder) -> AsnBuilder,

Add a nested SEQUENCE built with a closure.

pub fn set<F>(self, f: F) -> Self

where F: FnOnce(AsnBuilder) -> AsnBuilder,

Add a nested SET built with a closure.

pub fn value(self, v: AsnValue) -> Self

Add a raw pre-built AsnValue.

pub fn build(self) -> Vec<u8>

Build the accumulated items.

If there is exactly one item, returns its encoded form. If there are multiple items, wraps them in a SEQUENCE.

pub fn build_value(self) -> AsnValue

Build and return the items as an AsnValue::Sequence.

Trait Implementations

impl Default for AsnBuilder

Available on crate feature alloc only.

fn default() -> Self

Returns the “default value” for a type.
