errgo-ts/dist/coerce-error.d.ts

A lightweight error handling library inspired by Go and Rust.

/**
 * Ensures an unknown value is an `Error` instance, converting it if needed.
 *
 * @param e - unknown value to treat as an error.
 * @returns `e` unchanged if already an Error, otherwise converts `e` to an Error.
 *
 * @example
 * } catch (e: unknown) {
 *   // err is guaranteed to be an Error instance
 *   const err = coerceError(e);
 * }

export declare function coerceError(e: unknown): Error;
