Crate vouched_core 

Core error types used by vouched generated code.

Most users should depend on the facade crate, vouched, which re-exports these types together with the derive macro. This crate exists so generated code can refer to stable validation error types.

The important public pieces are:

• TooShortError and TooLongError for len(...) failures.
• InvalidCharError for chars(...) failures.
• OutOfRangeNumericError and NumericValue for numeric range(...) and cast(try_from(...)) failures.
• VouchedError, implemented by generated error enums.
• Error, an allocation-backed erased wrapper available with alloc.

Structs

Error

Wrapper type for handling different Vouched error types uniformly.

InvalidCharError

Error returned when a string newtype contains a character rejected by chars.

NumericValue

Lossless numeric value captured by generated range and cast errors.

OutOfRangeNumericError

Error returned when a numeric newtype is outside its range bounds.

TooLongError

Error returned when a string newtype is longer than its len upper bound.

TooShortError

Error returned when a string newtype is shorter than its len lower bound.

Traits

VouchedError

Common interface for generated Vouched errors.
