Struct ApptainerConfig 

pub struct ApptainerConfig {
    pub executable: String,
    pub image_cache_dir: Option<PathBuf>,
    pub extra_args: Vec<String>,
}

Configuration for the Apptainer container runtime.

Fields

executable: String

Path to the Apptainer (or Singularity) executable.

Defaults to "apptainer". Set to "singularity" or a full path (e.g., /usr/local/bin/apptainer) if the executable is not on PATH or if using Singularity instead.

image_cache_dir: Option<PathBuf>

Path to a shared directory for caching pulled .sif images.

When set, pulled images are stored in this directory and shared across runs. When unset, images are stored in a per-run directory that is not shared.

extra_args: Vec<String>

Additional command-line arguments to pass to apptainer exec when executing tasks.

Implementations

impl ApptainerConfig

pub async fn validate(&self) -> Result<(), Error>

Validate that Apptainer is appropriately configured.

Trait Implementations

impl Clone for ApptainerConfig

fn clone(&self) -> ApptainerConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApptainerConfig

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

Formats the value using the given formatter.

impl Default for ApptainerConfig

fn default() -> Self

Returns the “default value” for a type.

impl Eq for ApptainerConfig

impl<'de> FromToml<'de> for ApptainerConfig

fn from_toml( __ctx: &mut Context<'de>, __item: &Item<'de>, ) -> Result<Self, Failed>

Attempts to construct Self from a TOML Item.

impl PartialEq for ApptainerConfig

fn eq(&self, other: &ApptainerConfig) -> 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 StructuralPartialEq for ApptainerConfig

impl ToToml for ApptainerConfig

fn to_toml<'__de>( &'__de self, __arena: &'__de Arena, ) -> Result<Item<'__de>, ToTomlError>

Produces a TOML Item representing this value.

fn to_optional_toml<'a>( &'a self, arena: &'a Arena, ) -> Result<Option<Item<'a>>, ToTomlError>

Produces an optional TOML Item representing this value.
