Fields

function_name: String

function_arn: String

runtime: String

role: String

handler: String

description: String

timeout: i64

memory_size: i64

code_sha256: String

code_size: i64

version: String

last_modified: DateTime<Utc>

tags: BTreeMap<String, String>

environment: BTreeMap<String, String>

architectures: Vec<String>

package_type: String

code_zip: Option<Vec<u8>>

image_uri: Option<String>

Container image URI for PackageType=Image functions. Points at a private or public ECR image that the runtime pulls at invoke time. None for PackageType=Zip.

policy: Option<String>

Resource-based policy attached to this function via AddPermission, serialized as a full JSON policy document ({"Version":"2012-10-17","Statement":[...]}). None means the function has no resource policy attached, matching the ResourceNotFoundException AWS returns from GetPolicy in that state. AddPermission lazily initializes this; every RemovePermission leaves at least {"Statement":[]} behind, matching AWS behavior.

layers: Vec<AttachedLayer>

Layer versions attached to this function, in attach order. AWS extracts each layer’s content into /opt of the runtime sandbox at invoke time; fakecloud’s container runtime mirrors that via docker cp. code_size is captured at attach time from the referenced LayerVersion so GetFunctionConfiguration can echo it without a second state lookup; layer versions are immutable so the cached size never goes stale.

revision_id: String

RevisionId is a stable token AWS expects to round-trip through optimistic-concurrency calls (UpdateFunctionConfiguration, UpdateFunctionCode, AddPermission, …). It only changes when the function config changes; we used to mint a fresh UUID per function_config_json call which broke client-side ETag-style guards.

tracing_mode: Option<String>

TracingConfig.Mode — PassThrough (default) or Active.

kms_key_arn: Option<String>

KMSKeyArn for env-var encryption (defaults to AWS-managed aws/lambda when unset, which we represent as None).

ephemeral_storage_size: Option<i64>

EphemeralStorage.Size in MiB. AWS default is 512.

vpc_config: Option<Value>

VpcConfig (SubnetIds, SecurityGroupIds, Ipv6AllowedForDualStack). fakecloud doesn’t network-isolate; we just round-trip the shape.

snap_start: Option<Value>

SnapStart (ApplyOn, OptimizationStatus).

dead_letter_config_arn: Option<String>

DeadLetterConfig.TargetArn for async-invoke failures.

file_system_configs: Vec<Value>

FileSystemConfigs (EFS access points). Round-tripped only.

logging_config: Option<Value>

LoggingConfig (LogFormat, ApplicationLogLevel, SystemLogLevel, LogGroup).

image_config: Option<Value>

ImageConfigResponse.ImageConfig for container-package functions.

signing_profile_version_arn: Option<String>

SigningProfileVersionArn populated by code signing.

signing_job_arn: Option<String>

SigningJobArn populated by code signing.

runtime_version_config: Option<Value>

RuntimeVersionConfig (RuntimeVersionArn).

master_arn: Option<String>

MasterArn — only set on numbered versions; points at the parent $LATEST ARN.

state_reason: Option<String>

Free-form StateReason populated when the function is not in the happy Active/Successful path (e.g. image scan failed, KMS key disabled, code-signing rejection). None for normal functions.

state_reason_code: Option<String>

Machine-readable StateReasonCode paired with state_reason (Idle, Creating, Restoring, EniLimitExceeded, …).

durable_config: Option<Value>

DurableConfig for AWS’s durable-function feature (RetentionPeriodInDays, ExecutionTimeout). Round-tripped only — there’s no execution-history backend in fakecloud.

last_update_status_reason: Option<String>

Free-form LastUpdateStatusReason set on the most recent failed or in-progress configuration update.

last_update_status_reason_code: Option<String>

Machine-readable code paired with last_update_status_reason (EniLimitExceeded, InsufficientRolePermissions, …).
