Enum P2shItemError 

#[non_exhaustive]
pub enum P2shItemError {
    Malformed,
    TemplateEncoding,
    PlaceholderCount {
        placeholders: usize,
        keys: usize,
    },
    Multipath,
}

Errors in the structure of a ZIP 316 Revision 2 P2SH viewing key item.

The item payload encodes a BIP 388 wallet policy: a descriptor template followed by a vector of key information entries. Only the structure of the payload is validated; full validation of the descriptor template against the BIP 388 grammar is the responsibility of consumers that interpret the policy.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Malformed

The item payload is not a well-formed encoding of a descriptor template and key information vector.

TemplateEncoding

The descriptor template is not US-ASCII.

PlaceholderCount

The key placeholders in the descriptor template do not correspond one-to-one with the entries of the key information vector.

Fields

placeholders: usize

The number of @N key placeholders in the descriptor template.

keys: usize

The number of entries in the key information vector.

Multipath

A key placeholder is not followed by the multipath notation required for the containing key kind (/** in a UFVK, /* in a UIVK).
