Expand description

Errors that can occur when serializing a type.

Variants

UnsupportedType

Indicates that a Rust type was requested to be serialized but it was not supported.

Currently the TOML format does not support serializing types such as enums, tuples and tuple structs.

KeyNotString

The key of all TOML maps must be strings, but serialization was attempted where the key of a map was not a string.

ValueAfterTable

All values in a TOML table must be emitted before further tables are emitted. If a value is emitted after a table then this error is generated.

DateInvalid

A serialized date was invalid.

NumberInvalid

A serialized number was invalid.

UnsupportedNone

None was attempted to be serialized, but it’s not supported.

Custom(String)

A custom error which could be generated when serializing a particular type.
