Enum Schema 

#[non_exhaustive]
pub enum Schema {
    Opaque,
    Unit,
    Bool,
    Unsigned(u8),
    Signed(u8),
    Float(u8),
    Bytes(usize),
    Text(usize),
    List(&'static Schema, usize),
    Array(&'static Schema, usize),
    Option(&'static Schema),
    Result(&'static Schema, &'static Schema),
    Record(&'static [Field]),
    Enum(&'static [Variant]),
}

Finite type metadata, emitted by Wire derives and bounded built-ins. Manual Wire implementations default to Opaque and cannot generate bindings.

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.

Opaque

No trustworthy generated projection is available.

Unit

Zero-byte unit.

Bool

A strict boolean byte.

Unsigned(u8)

Unsigned integer width in bits.

Signed(u8)

Signed integer width in bits (i8 is a raw two’s-complement byte).

Float(u8)

Finite IEEE-754 width in bits (32 or 64); preserves signed zero.

Bytes(usize)

Bytes with a maximum length.

Text(usize)

UTF-8 text with a maximum byte length.

List(&'static Schema, usize)

Element schema and maximum count.

Array(&'static Schema, usize)

Element schema and exact count, without a length prefix.

Option(&'static Schema)

Optional value, with explicit None/Some tags.

Result(&'static Schema, &'static Schema)

Ok and Err payloads respectively.

Record(&'static [Field])

Fields in their explicit wire order.

Enum(&'static [Variant])

Alternatives selected by explicit transmitted IDs.
