Expand description

Owned form of ASN.1 BIT STRING type.

This type provides the same functionality as BitStringRef but owns the backing data.

Implementations§

Maximum number of unused bits allowed.

Create a new ASN.1 BIT STRING from a byte slice.

Accepts an optional number of “unused bits” (0-7) which are omitted from the final octet. This number is 0 if the value is octet-aligned.

Create a new ASN.1 BIT STRING from the given bytes.

The “unused bits” are set to 0.

Get the number of unused bits in the octet serialization of this BIT STRING.

Is the number of unused bits a value other than 0?

Get the length of this BIT STRING in bits.

Is the inner byte slice empty?

Borrow the inner byte slice.

Returns None if the number of unused bits is not equal to zero, i.e. if the BIT STRING is not octet aligned.

Use BitString::raw_bytes to obtain access to the raw value regardless of the presence of unused bits.

Borrow the raw bytes of this BIT STRING.

Iterator over the bits of this BIT STRING.
