Implementations

impl Vmt

pub fn new(shader: &str) -> Self

Creates a new empty VMT with the specified shader.

pub fn from_str(input: &str) -> Result<Self, Error>

Parses VMT from a string using AST parser to handle root-level shader.

pub fn from_file<P: AsRef<Path>>(path: P) -> Result<Self, Error>

Parses VMT from a file.

pub fn set_string(&mut self, key: &str, value: &str) -> &mut Self

Set a string property. Overwrites if exists.

pub fn set_flag(&mut self, key: &str, enabled: bool) -> &mut Self

Set a flag (boolean) property (converts to “1” or “0”).

pub fn remove(&mut self, key: &str) -> &mut Self

Removes a property by key, checking for $, % and raw name.

pub fn get_raw(&self, key: &str) -> Option<&Value>

O(1) lookup. Handles $, % prefixes and case-insensitive keys.

pub fn get_string(&self, key: &str) -> Option<String>

Get value as string if it exists.

pub fn get_f32(&self, key: &str) -> Option<f32>

Safely gets a value and parses it as f32.

pub fn get_i32(&self, key: &str) -> Option<i32>

Safely gets a value and parses it as i32.

pub fn get_bool(&self, key: &str) -> bool

Checks boolean flags: supports “1”, “true”, “yes”.

pub fn get_color(&self, key: &str) -> Option<[f32; 3]>

Parses colors/vectors in both [0.0 0.0 0.0] and {255 255 255} formats. Returns a normalized [f32; 3] (0.0 to 1.0).

pub fn add_proxy<'a, I>(&mut self, name: &str, params: I) -> &mut Self

where I: IntoIterator<Item = (&'a str, &'a str)>,

Adds a proxy to the material.

pub fn to_string(&self) -> Result<String, Error>

Serializes the VMT back into a KeyValues string.

pub fn to_file<P: AsRef<Path>>(&self, path: P) -> Result<(), Error>

Serializes the VMT and writes it to a file.

impl Vmt

pub fn get_block<T: DeserializeOwned>( &self, key: &str, ) -> Result<Option<T>, Error>

Deserializes a specific block into a Serde-compatible struct.

impl Vmt

pub fn proxies(&self) -> Vec<Proxy>

Extracts and flattens all proxies into an ordered list.

impl Vmt

pub fn apply_patch(&mut self, patch: &Vmt)

Applies patch instructions (insert/replace) to this VMT.

Trait Implementations

impl Clone for Vmt

fn clone(&self) -> Vmt

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Vmt

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Vmt

fn eq(&self, other: &Vmt) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
