Struct NoteValue

Source 
pub struct NoteValue(/* private fields */);
Expand description

The non-negative value of an individual Sapling note.

Implementations§

Source§

impl NoteValue

Source

pub const ZERO: NoteValue

The zero note value.

Source

pub fn inner(&self) -> u64

Returns the raw underlying value.

Source

pub fn from_raw(value: u64) -> Self

Creates a note value from its raw numeric value.

This only enforces that the value is an unsigned 64-bit integer. Callers should enforce any additional constraints on the value’s valid range themselves.
