Stack input definition serialized into a release stack.

Fields

id: String

Stable input ID used by CLI/API calls.

kind: StackInputKind

Input primitive kind.

provided_by: Vec<StackInputProvider>

Who can provide this value.

required: bool

Whether a resolved value is required before deployment can proceed.

label: String

Human-facing field label.

description: String

Human-facing helper text.

placeholder: Option<String>

Example placeholder shown in UI.

default: Option<StackInputDefaultValue>

Default value for optional/plain inputs.

platforms: Option<Vec<Platform>>

Platforms where this input applies.

when: Option<StackInputCondition>

Only applies when the referenced boolean resolves to the given value. Inactive inputs ignore provided values, validation and environment mappings.

validation: Option<StackInputValidation>

Portable validation constraints.

generate: Option<StackInputGenerate>

Alien generates the value when none is provided. Secret, developer-provided inputs only.

env: Vec<StackInputEnvironmentMapping>

Runtime env-var mappings for v1 input resolution.

Implementations

impl StackInputDefinition

pub fn applies_to(&self, platform: Platform) -> bool

Whether this input is available on the deployment platform, independently of its base cloud. Empty scopes retain their legacy all-platform meaning for existing releases. Build-time checks reject empty scopes in new releases.

pub fn applies( &self, inputs: &[StackInputDefinition], values: &HashMap<String, Value>, platform: Platform, ) -> bool

Whether this input applies, using the referenced input’s provided value or boolean default. An off-platform reference resolves to false; an unanswered reference never matches. Definitions must pass release preflights first.

pub fn controls_input( &self, inputs: &[StackInputDefinition], include: impl Fn(&StackInputDefinition) -> bool, ) -> bool

Whether this input controls any input selected by the caller.

pub fn is_generated(&self) -> bool

Whether Alien generates this input’s value when none is provided. A generated input never needs a value from the developer or deployer.

Trait Implementations

impl Clone for StackInputDefinition

fn clone(&self) -> Self

Returns a duplicate of the value.
