Struct CodegenOptions 

pub struct CodegenOptions {
    pub exclude_global_allow_pragmas: bool,
    pub prefixes: Vec<Prefix>,
    pub emit_logging: bool,
    pub split_match_arms: bool,
    pub match_arm_split_threshold: Option<usize>,
}

Options for code generation.

Fields

exclude_global_allow_pragmas: bool

Do not include the #![allow(...)] pragmas in the generated source. Useful if it must be include!()’d elsewhere.

prefixes: Vec<Prefix>

Prefixes to remove when printing file names in generaed files. This helps keep codegen deterministic.

emit_logging: bool

Emit log::debug! and log::trace! invocations in the generated code to help debug rule matching and execution.

In Cranelift this is typically controlled by a cargo feature on the crate that includes the generated code (e.g. cranelift-codegen).

split_match_arms: bool

Split large match arms into local closures when generating iterator terms.

In Cranelift this is typically controlled by a cargo feature on the crate that includes the generated code (e.g. cranelift-codegen).

match_arm_split_threshold: Option<usize>

Threshold for splitting match arms into local closures.

If None, a default threshold is used.
