Struct DecodedHeader

pub struct DecodedHeader<'a> {
    pub state_reads: &'a [u8],
    pub constraints: &'a [u8],
}

The header of a Predicate decoded. This contains the indices of the Predicate’s data in a buffer.

Fields

state_reads: &'a [u8]

The indices of the state read programs in a buffer.

constraints: &'a [u8]

The indices of the constraint check programs in a buffer.

Implementations

impl<'a> DecodedHeader<'a>

pub fn bytes_len(&self) -> usize

The number of bytes this header points to.

This includes the EncodedFixedSizeHeader::SIZE and the lengths of the programs as well as the programs themselves.

pub fn decode(buf: &'a [u8]) -> Result<Self, DecodeError>

Decode a header from bytes.

Errors

Returns an error if the buffer is too small or the header is inconsistent or the predicate bounds are beyond the limits.

Trait Implementations

impl<'a> Clone for DecodedHeader<'a>

fn clone(&self) -> DecodedHeader<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for DecodedHeader<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for DecodedHeader<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for DecodedHeader<'a>

fn eq(&self, other: &DecodedHeader<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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