Enum NumStorageItems 

pub enum NumStorageItems {
    Exact(usize),
    Range {
        min: usize,
        max: usize,
    },
    AnyOf(&'static [NumStorageItems]),
}

The number of storage items a StandardNote accepts.

A note script asserts the size of the storage it is handed, and some scripts accept more than one size: they branch on it, or hold a variable-length tail. This is the set of sizes one of them accepts, so that a caller can check a note against it instead of comparing against a single constant.

Variants

Exact(usize)

The note holds exactly this many storage items.

Range

The note holds any number of storage items in this inclusive range.

Fields

min: usize

max: usize

AnyOf(&'static [NumStorageItems])

The note holds a number of storage items accepted by any of these, and by none of the sizes in between them.
