Struct Config 

pub struct Config { /* private fields */ }

Configuration for Flow type generation.

Implementations

impl Config

pub fn new() -> Self

Create a new config with default settings.

pub fn from_env() -> Self

Read config from environment variables.

Variable	Default
FLOW_RS_EXPORT_DIR	./bindings
FLOW_RS_FILE_EXTENSION	js.flow
FLOW_RS_LARGE_INT	bigint

pub fn with_out_dir(self, dir: impl Into<PathBuf>) -> Self

Set the export directory.

pub fn out_dir(&self) -> &Path

Return the export directory.

pub fn with_array_tuple_limit(self, limit: usize) -> Self

Set the maximum size of arrays up to which they are treated as Flow tuples. Arrays beyond this size will instead result in a $ReadOnlyArray<T>.

Default: 64

pub fn array_tuple_limit(&self) -> usize

Return the maximum size of arrays treated as tuples.

pub fn with_file_extension(self, ext: impl Into<String>) -> Self

Set the file extension for generated Flow files.

This is determined by your project’s JS module system:

• "js.flow" — standard
• "cjs.flow" — CommonJS
• "mjs.flow" — ES modules

pub fn file_extension(&self) -> &str

Return the file extension for generated files.

pub fn with_large_int(self, ty: impl Into<String>) -> Self

Set the Flow type used for large integers (i64, u64, i128, u128).

Default: "bigint" (matches ts-rs)

pub fn large_int(&self) -> &str

Return the Flow type for large integers.

pub fn resolve_output_path(&self, base: &Path) -> PathBuf

Resolve a type’s base output path (without extension) into a full path with extension.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.
