Function.safeTry
resultar / safeTry
safeTry<
T,E>(body):Result<T,E>
Evaluates the given generator to a Result returned or an Err yielded from it, whichever comes first.
This function, in combination with Result.safeUnwrap(), is intended to emulate
Rust's ? operator.
See /tests/safeTry.test.ts for examples.
• T
• E
• body
What is evaluated. In body, yield* result.safeUnwrap() works as
Rust's result? expression.
Result<T, E>
The first occurence of either an yielded Err or a returned Result.
safeTry<
YieldErr,GeneratorReturnResult>(body):Result<InferOkTypes<GeneratorReturnResult>,InferErrTypes<YieldErr> |InferErrTypes<GeneratorReturnResult>>
• YieldErr extends Result<never, unknown>
• GeneratorReturnResult extends Result<unknown, unknown>
• body
Result<InferOkTypes<GeneratorReturnResult>, InferErrTypes<YieldErr> | InferErrTypes<GeneratorReturnResult>>
safeTry<
T,E>(body):ResultAsync<T,E>
Evaluates the given generator to a Result returned or an Err yielded from it, whichever comes first.
This function, in combination with Result.safeUnwrap(), is intended to emulate
Rust's ? operator.
See /tests/safeTry.test.ts for examples.
• T
• E
• body
What is evaluated. In body, yield* result.safeUnwrap() and
yield* resultAsync.safeUnwrap() work as Rust's result? expression.
ResultAsync<T, E>
The first occurence of either an yielded Err or a returned Result.
safeTry<
YieldErr,GeneratorReturnResult>(body):ResultAsync<InferOkTypes<GeneratorReturnResult>,InferErrTypes<YieldErr> |InferErrTypes<GeneratorReturnResult>>
• YieldErr extends Result<never, unknown>
• GeneratorReturnResult extends Result<unknown, unknown>
• body
ResultAsync<InferOkTypes<GeneratorReturnResult>, InferErrTypes<YieldErr> | InferErrTypes<GeneratorReturnResult>>
