Struct ShaderTemplateV2 

pub struct ShaderTemplateV2 {
    pub source: String,
    pub defines: HashMap<String, String>,
}

A parameterised shader template that replaces #define KEY tokens.

Instantiation replaces occurrences of each key found in defines with the corresponding value. The key must appear as a whole word (surrounded by non-identifier characters or at start/end of line).

Fields

source: String

Raw template source text.

defines: HashMap<String, String>

Map from token name to replacement value.

Implementations

impl ShaderTemplateV2

pub fn new(source: impl Into<String>, defines: HashMap<String, String>) -> Self

Create a new template with the given source and defines.

pub fn instantiate(&self) -> String

Instantiate the template by performing all #define substitutions.

Each entry in defines replaces all occurrences of the key in the source with the corresponding value.
