Module ser 

Serde serializer for structprop documents. Serde Serializer for the structprop format.

The public entry point is to_string. Internally a Serializer walks the serde data model and writes structprop text directly into an output String.

Type mapping

Rust / serde	Structprop output
bool	true or false scalar
i8–i64, u8–u64	bare integer scalar (e.g. 42, -7)
f32, f64	bare float scalar (e.g. 3.14)
char	bare single-character scalar (quoted if the character is special)
String / &str	bare scalar, or "quoted" if it contains spaces, tabs, newlines, carriage returns, #, {, }, or =, or is empty; yields Error::UnsupportedType if the value requires quoting and contains ", or if the value starts with "
None / () / unit struct	null scalar
newtype struct	transparent — serializes as the inner value
struct / map	key { … } block at the current indentation level
Vec<T> / sequence / tuple / tuple struct	= { … } inline list
unit enum variant	bare variant name scalar
newtype enum variant	variant_name = <scalar or list>
tuple enum variant	variant_name = { … } list
struct enum variant	variant_name { … } block

Structs

MapSerializer

ser::SerializeMap (and struct impls) that writes key = value / key { … } entries one at a time.

SeqSerializer

ser::SerializeSeq (and related tuple impls) that collects rendered items then emits them as a { … } block.

Serializer

Core serializer that accumulates structprop text in output.

Functions
