Enum TempStoragePolicy 

pub enum TempStoragePolicy {
    Disabled,
    Directory {
        root: PathBuf,
        max_bytes: u64,
    },
}

Policy controlling whether and where execution may spill temporary data.

Variants

Disabled

Operations that cannot remain within memory must return an error.

Directory

Spill files may be created below one explicit directory.

Fields

root: PathBuf

Root below which implementations create execution-specific files.

max_bytes: u64

Maximum bytes retained on disk by one execution context.

Implementations

impl TempStoragePolicy

pub fn directory(root: impl Into<PathBuf>, max_bytes: u64) -> Self

Enables bounded spill below root.

pub fn root(&self) -> Option<&Path>

Returns the configured spill root, when disk storage is enabled.

pub const fn max_bytes(&self) -> u64

Returns the disk-space ceiling. Disabled storage has a zero ceiling.
