TermValue

Struct TermValue 

Source
pub struct TermValue { /* private fields */ }
Expand description

Wiki ADR-029: a single Term variant’s evaluated value, carried as a fixed-capacity byte buffer with an active-prefix length. The catamorphism produces a TermValue per variant, propagated up the term tree by the per-variant fold rules.

Implementations§

Source§

impl TermValue

Source

pub const fn empty() -> TermValue

Construct an empty TermValue (length zero).

Source

pub const fn from_slice(bytes: &[u8]) -> TermValue

Construct a TermValue from a slice; copies up to TERM_VALUE_MAX_BYTES bytes.

Source

pub const fn from_u64_be(value: u64, width: usize) -> TermValue

ADR-051: construct a TermValue from a u64 value at a declared byte width. The high (8 - width) bytes of the u64 are discarded; the low width bytes are written into the value buffer in big-endian order.

Source

pub const fn from_slice_const(bytes: &[u8; 4096], len: usize) -> TermValue

ADR-051 helper: const-constructor from a prepared big-endian byte buffer. len MUST be <= TERM_VALUE_MAX_BYTES; the function copies the first len bytes of bytes and records len as the active prefix.

Source

pub const fn bytes(&self) -> &[u8]

Returns the active byte prefix.

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

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