Struct aws_sdk_servicecatalog::model::ParameterConstraints

#[non_exhaustive]
pub struct ParameterConstraints {
    pub allowed_values: Option<Vec<String>>,
    pub allowed_pattern: Option<String>,
    pub constraint_description: Option<String>,
    pub max_length: Option<String>,
    pub min_length: Option<String>,
    pub max_value: Option<String>,
    pub min_value: Option<String>,
}

The constraints that the administrator has put on the parameter.

Fields (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>>

The values that the administrator has allowed for the parameter.

allowed_pattern: Option<String>

A regular expression that represents the patterns that allow for String types. The pattern must match the entire parameter value provided.

constraint_description: Option<String>

A string that explains a constraint when the constraint is violated. For example, without a constraint description, a parameter that has an allowed pattern of [A-Za-z0-9]+ displays the following error message when the user specifies an invalid value:

Malformed input-Parameter MyParameter must match pattern [A-Za-z0-9]+

By adding a constraint description, such as must only contain letters (uppercase and lowercase) and numbers, you can display the following customized error message:

Malformed input-Parameter MyParameter must only contain uppercase and lowercase letters and numbers.

max_length: Option<String>

An integer value that determines the largest number of characters you want to allow for String types.

min_length: Option<String>

An integer value that determines the smallest number of characters you want to allow for String types.

max_value: Option<String>

A numeric value that determines the largest numeric value you want to allow for Number types.

min_value: Option<String>

A numeric value that determines the smallest numeric value you want to allow for Number types.

Implementations

impl ParameterConstraints

pub fn allowed_values(&self) -> Option<&[String]>

The values that the administrator has allowed for the parameter.

pub fn allowed_pattern(&self) -> Option<&str>

A regular expression that represents the patterns that allow for String types. The pattern must match the entire parameter value provided.

pub fn constraint_description(&self) -> Option<&str>

A string that explains a constraint when the constraint is violated. For example, without a constraint description, a parameter that has an allowed pattern of [A-Za-z0-9]+ displays the following error message when the user specifies an invalid value:

Malformed input-Parameter MyParameter must match pattern [A-Za-z0-9]+

By adding a constraint description, such as must only contain letters (uppercase and lowercase) and numbers, you can display the following customized error message:

Malformed input-Parameter MyParameter must only contain uppercase and lowercase letters and numbers.

pub fn max_length(&self) -> Option<&str>

An integer value that determines the largest number of characters you want to allow for String types.

pub fn min_length(&self) -> Option<&str>

An integer value that determines the smallest number of characters you want to allow for String types.

pub fn max_value(&self) -> Option<&str>

A numeric value that determines the largest numeric value you want to allow for Number types.

pub fn min_value(&self) -> Option<&str>

A numeric value that determines the smallest numeric value you want to allow for Number types.

impl ParameterConstraints

pub fn builder() -> Builder

Creates a new builder-style object to manufacture ParameterConstraints

Trait Implementations

impl Clone for ParameterConstraints

fn clone(&self) -> ParameterConstraints

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
