Struct Boolean 

Source 
pub struct Boolean {
    pub value: u8,
}
Expand description

ASN.1 BOOLEAN type

BER objects consider any non-zero value as true, and 0 as false.

DER objects must use value 0x0 (false) or 0xff (true).

Fields§

§value: u8

Implementations§

Source§

impl Boolean

Source

pub const FALSE: Boolean

BOOLEAN object for value false

Source

pub const TRUE: Boolean

BOOLEAN object for value true

Source

pub const fn new(value: u8) -> Self

Create a new Boolean from the provided logical value.

Source

pub const fn bool(&self) -> bool

Return the bool value from this object.

Trait Implementations§

Source§

impl CheckDerConstraints for Boolean

Source§

fn check_constraints(any: &Any<'_>) -> Result<()>

Source§

impl Debug for Boolean

Source§

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

Formats the value using the given formatter. Read more
Source§

impl PartialEq for Boolean

Source§

fn eq(&self, other: &Boolean) -> bool

Tests for self and other values to be equal, and is used by ==.
1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
Source§

impl Tagged for Boolean

Source§

const TAG: Tag = Tag::Boolean

Source§

impl ToDer for Boolean

Source§

fn write_der_raw(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Similar to using to_der, but uses header without computing length value

Source§

fn to_der_len(&self) -> Result<usize>

Get the length of the object (including the header), when encoded
Source§

fn write_der_header(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER header to this writer.
Source§

fn write_der_content(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER content (all except header) to this writer.
Source§

fn to_der_vec(&self) -> SerializeResult<Vec<u8>>

Write the DER encoded representation to a newly allocated Vec<u8>.
Source§

fn to_der_vec_raw(&self) -> SerializeResult<Vec<u8>>

Similar to using to_vec, but uses provided values without changes. This can generate an invalid encoding for a DER object.
Source§

fn write_der(&self, writer: &mut dyn Write) -> SerializeResult<usize>

Attempt to write the DER encoded representation (header and content) into this writer. Read more
