Expand description
Errors that can occur when serializing a type.
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.
The key of all TOML maps must be strings, but serialization was
attempted where the key of a map was not a string.
Arrays in TOML must have a homogenous type, but a heterogeneous array
was emitted.
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.
A serialized date was invalid.
A serialized number was invalid.
None was attempted to be serialized, but it’s not supported.
A custom error which could be generated when serializing a particular
type.

and should not be overridden without very good reason.
