Struct Function 

pub struct Function {
    pub id: String,
    pub links: Vec<ResourceRef>,
    pub triggers: Vec<FunctionTrigger>,
    pub permissions: String,
    pub code: FunctionCode,
    pub memory_mb: u32,
    pub timeout_seconds: u32,
    pub environment: HashMap<String, String>,
    pub ingress: Ingress,
    pub arc_enabled: bool,
    pub concurrency_limit: Option<u32>,
    pub readiness_probe: Option<ReadinessProbe>,
}

Represents a serverless function that executes code in response to triggers or direct invocations. Functions are the primary compute resource in serverless applications, designed to be stateless and ephemeral.

Fields

id: String

Identifier for the function. Must contain only alphanumeric characters, hyphens, and underscores ([A-Za-z0-9-_]). Maximum 64 characters.

links: Vec<ResourceRef>

List of resource references this function depends on.

triggers: Vec<FunctionTrigger>

List of triggers that define what events automatically invoke this function. If empty, the function is only invokable directly via HTTP calls or platform-specific invocation APIs. When configured, the function will be automatically invoked when any of the specified trigger conditions are met.

permissions: String

Permission profile name that defines the permissions granted to this function. This references a profile defined in the stack’s permission definitions.

code: FunctionCode

Code for the function, either a pre-built image or source code to be built.

memory_mb: u32

Memory allocated to the function in megabytes (MB). Constraints: 128‑32768 MB (platform-specific limits may apply) Default: 256

timeout_seconds: u32

Maximum execution time for the function in seconds. Constraints: 1‑3600 seconds (platform-specific limits may apply) Default: 30

environment: HashMap<String, String>

Key-value pairs to set as environment variables for the function.

ingress: Ingress

Controls network accessibility of the function.

arc_enabled: bool

Whether the function can be invoked via ARC (Alien Remote Call) protocol from the control plane. When enabled, the necessary queue infrastructure is automatically created for the target platform.

concurrency_limit: Option<u32>

Maximum number of concurrent executions allowed for the function. None means platform default applies.

readiness_probe: Option<ReadinessProbe>

Optional readiness probe configuration. Only applicable for functions with Public ingress. When configured, the probe will be executed after provisioning/update to verify the function is ready.

Implementations

impl Function

pub fn new(id: String) -> FunctionBuilder

Create an instance of Function using the builder syntax

impl Function

pub const RESOURCE_TYPE: ResourceType

The resource type identifier for Functions

pub fn get_permissions(&self) -> &str

Returns the permission profile name for this function.

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Function

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Function

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Function

fn eq(&self, other: &Function) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ResourceDefinition for Function

fn resource_type() -> ResourceType

Returns the static type identifier for this resource type (e.g., “Function”, “Storage”)

fn get_resource_type(&self) -> ResourceType

Returns the resource type for this instance (calls the static method)

fn id(&self) -> &str

Returns the unique identifier for this specific resource instance

fn get_dependencies(&self) -> Vec<ResourceRef>

Returns the list of other resources this resource depends on

fn get_permissions(&self) -> Option<&str>

Returns the permission profile name for this resource, if it has one.

fn validate_update(&self, new_config: &dyn ResourceDefinition) -> Result<()>

Validates if an update from the current configuration to a new configuration is allowed

fn as_any(&self) -> &dyn Any

Provides access to the underlying concrete type for downcasting

fn as_any_mut(&mut self) -> &mut dyn Any

Provides mutable access to the underlying concrete type for downcasting

fn box_clone(&self) -> Box<dyn ResourceDefinition>

Creates a boxed clone of this resource definition

fn resource_eq(&self, other: &dyn ResourceDefinition) -> bool

For equality comparison between resource definitions

impl Serialize for Function

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Function

impl StructuralPartialEq for Function
