Module constraint

Constraints defined by this crate

For each constraint the possible error codes are defined as a set of constants. The name of the constants follow the naming convention:

INVALID_<constraint-name>[_<variant>]

The part is optional and only present if the constraint has some variants. The name of a constraint and its variants is converted to screaming snake case. The string values of the error codes follow a similar naming convention but use a dash (-) instead of the underscore to separate terms. Thus the codes are compatible with the convention used in the fluent project.

Structs

AssertFalse

The value must be false.

AssertTrue

The value must be true.

Contains

The value must contain the specified member or the specified member must be part of the value.

Digits

Maximum number of allowed integer digits and fraction digits.

MustMatch

Two related fields must be equal.

NonZero

Values of zero are not allowed.

NotEmpty

The value must not be empty.

Pattern

The value must match some regular expression.

Enums

Bound

The value must be within some bounds.

CharCount

The number of characters must be within some bounds.

Length

The length of a value must be within some bounds.

MustDefineRange

Two related fields must define a range.

Constants
