#[non_exhaustive]pub struct ParameterConstraints {
pub allowed_values: Option<Vec<String>>,
}
Expand description
A set of criteria that CloudFormation uses to validate parameter values. Although other constraints might be defined in the stack template, CloudFormation returns only the AllowedValues
property.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.allowed_values: Option<Vec<String>>
A list of values that are permitted for a parameter.
Implementations§
source§impl ParameterConstraints
impl ParameterConstraints
sourcepub fn allowed_values(&self) -> &[String]
pub fn allowed_values(&self) -> &[String]
A list of values that are permitted for a parameter.
If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .allowed_values.is_none()
.

impl ParameterConstraints
sourcepub fn builder() -> ParameterConstraintsBuilder
pub fn builder() -> ParameterConstraintsBuilder
Creates a new builder-style object to manufacture ParameterConstraints
.
