Struct ParameterInfo 

pub struct ParameterInfo {
    pub param_type: String,
    pub default: Option<String>,
    pub allowed_values: Option<Vec<String>>,
    pub allowed_pattern: Option<String>,
    pub min_length: Option<u64>,

    pub description: Option<String>,
    pub no_echo: bool,

    pub default_matches_allowed_pattern: Option<bool>,
}

A template Parameter’s declaration: its type, constraints (allowed values/pattern, length and value bounds), default, and description.

Fields

param_type: String

The parameter’s declared CloudFormation type (for example String, Number, or an AWS-specific type); defaults to String when the template omits Type.

default: Option<String>

allowed_values: Option<Vec<String>>

allowed_pattern: Option<String>

min_length: Option<u64>

max_length: Option<u64>

min_value: Option<i64>

max_value: Option<i64>

description: Option<String>

no_echo: bool

Whether the parameter is declared with NoEcho, meaning its value is masked in CloudFormation output.

allowed_pattern_valid: Option<bool>

Whether the AllowedPattern is a valid, supported regular expression; absent when no AllowedPattern is declared.

default_matches_allowed_pattern: Option<bool>

Whether the Default value satisfies the AllowedPattern; absent unless both a Default and an AllowedPattern are declared.
