Enum FoamValue 

pub enum FoamValue {
    Scalar(f64),
    Word(String),
    Str(String),
    List(Vec<FoamValue>),
    Dict(FoamDict),
}

A leaf value inside a list or a bare token sequence.

Variants

Scalar(f64)

A numeric scalar.

Word(String)

A bare identifier / keyword-like word (e.g. ascii, Gauss, PCG, or a function-style grad(U)).

Str(String)

A "…" quoted string (stored without the surrounding quotes).

List(Vec<FoamValue>)

A parenthesised ( … ) list of values (may nest).

Dict(FoamDict)

A { … } sub-dictionary appearing as a list element.

OpenFOAM lists routinely carry dictionaries: constant/polyMesh/boundary and cellZones are N ( name { … } name { … } ), and GeN-Foam’s nuclearData writes its states and zones the same way. Without this variant the braces tokenise into stray Words and the entry silently flattens into nonsense rather than failing.

The name preceding each such dictionary is a separate Word element in the enclosing list — this variant holds only the braced body, exactly as the grammar has it.

Implementations

impl FoamValue

pub fn as_vector3(&self) -> Option<Vector3>

Interpret a List of exactly three scalars as a Vector3; returns None for any other shape.

pub fn as_scalar(&self) -> Option<f64>

The scalar value, if this is a FoamValue::Scalar.

pub fn as_word(&self) -> Option<&str>

The word text, if this is a FoamValue::Word.
