Struct DeserializeOptions 

#[non_exhaustive]
pub struct DeserializeOptions {
    pub deny_unsupported_types: bool,
    pub deny_recursive_tables: bool,
    pub sort_keys: bool,
    pub encode_empty_tables_as_array: bool,
    pub detect_mixed_tables: bool,
}

Available on crate feature serde only.

A struct with options to change default deserializer behavior.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

deny_unsupported_types: bool

If true, an attempt to serialize types such as Function, Thread, LightUserData and Error will cause an error. Otherwise these types skipped when iterating or serialized as unit type.

Default: true

deny_recursive_tables: bool

If true, an attempt to serialize a recursive table (table that refers to itself) will cause an error. Otherwise subsequent attempts to serialize the same table will be ignored.

Default: true

sort_keys: bool

If true, keys in tables will be iterated in sorted order.

Default: false

encode_empty_tables_as_array: bool

If true, empty Lua tables will be encoded as array, instead of map.

Default: false

detect_mixed_tables: bool

If true, enable detection of mixed tables.

A mixed table is a table that has both array-like and map-like entries or several borders. See The Length Operator documentation for details about borders.

When this option is disabled, a table with a non-zero length (with one or more borders) will be always encoded as an array.

Default: false
