Struct EffectExpression 

pub struct EffectExpression { /* private fields */ }

A parsed representation of a tachyonfx effect expression.

EffectExpression provides a way to parse and represent effect descriptions in string form. This allows effects to be defined using a domain-specific language (DSL) syntax and later converted into actual effect instances.

Examples

use tachyonfx::dsl::EffectExpression;

// Parse a simple fade effect
let expr = EffectExpression::parse("fx::fade_to(Color::from_u32(0), (500, Linear))").unwrap();

// Parse a more complex effect chain
let expr = EffectExpression::parse(r#"
    fx::sequence(&[
        fx::fade_from(Color::Black, Color::from_u32(0), (1000, QuadOut)),
        fx::dissolve((500, BounceOut))
    ])
"#);

Implementations

impl EffectExpression

pub fn parse(input: &str) -> Result<Self, DslError>

Parses a string into an EffectExpression.

This method takes a string containing a tachyonfx effect description and attempts to parse it into a structured EffectExpression. The input string should follow the tachyonfx DSL syntax.

Arguments

• input - A string slice containing the effect expression to parse

Returns

Returns a Result containing either:

• Ok(EffectExpression) if parsing was successful
• Err(DslError) if the input could not be parsed

Errors

Returns DslError if tokenization or AST parsing fails.

Trait Implementations

impl Display for EffectExpression

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

Formats the value using the given formatter.
