Module coercion 

CloudFormation stringifies all scalar values before sending them to resource handlers, so 512 and "512" are equivalent. YAML 1.1 also parses yes/no as booleans. These helpers implement the same loose type semantics so that constraint checks (min/max, enum, pattern, length) work on coerced values.

Enums

CoerceResult

Result of attempting to coerce a JSON value to match an expected schema type.

Functions

coerce_port_to_string

Stringify a value for port-style comparison, accepting only string and integer scalars.

coerce_str_to_integer

The string arm of coerce_to_integer, for callers that hold a scalar outside a serde_json::Value (such as the parser’s ParseValue values).

coerce_string_or_integer_to_string

Returns the text authored for a string or integer scalar. Fractional numbers, booleans, nulls, and composite values have no string-or-integer form.

coerce_to_bool

Accepts YAML 1.1 boolean strings in addition to native bools.

coerce_to_integer

coerce_to_number

coerce_to_string

coerce_value

Attempt to coerce a JSON value to match the expected schema type.

scalar_eq

Whether two values are equal under CloudFormation’s loose scalar semantics.

type_compatible

Check if a value is compatible with the expected JSON Schema type using CFN’s loose semantics.
