Enum MetadataValue 

#[non_exhaustive]
pub enum MetadataValue {
    Bool(bool),
    I64(i64),
    U64(u64),
    F64(f64),
    String(String),
    Bytes(BString),
    Path(PathBuf),
}

An owned scalar value in a Metadata dictionary. Bytes and native paths retain their original representation.

Debug formatting keeps the variant and its value on a single line, even in pretty output.

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.

Bool(bool)

A boolean.

I64(i64)

A signed integer.

U64(u64)

An unsigned integer.

F64(f64)

A floating-point number.

String(String)

UTF-8 text.

Bytes(BString)

An arbitrary byte string.

Path(PathBuf)

A native filesystem path.
