Struct OwnedContainerProfile 

pub struct OwnedContainerProfile { /* private fields */ }

Performance and storage behavior applied only to harness-owned containers.

The default profile is intended for disposable test data: it passes --no-sync through the Docker Official PostgreSQL image’s POSTGRES_INITDB_ARGS interface and mounts a size-bounded tmpfs at the image’s PostgreSQL volume parent. External-server mode ignores this profile.

Custom images must implement the same environment-variable, filesystem, command, and mapped-TCP contracts as the Docker Official PostgreSQL 18 image. Disable either optimization when a compatible custom image or Docker daemon cannot provide it.

This type remains available without the containers feature so shared configuration code can compile, but external-only startup ignores it.

Implementations

impl OwnedContainerProfile

pub const fn performance() -> Self

Returns the default disposable-data performance profile.

pub const fn with_initdb_no_sync(self, enabled: bool) -> Self

Enables or disables initdb --no-sync for an owned container.

Disable this for custom images that do not honor POSTGRES_INITDB_ARGS. This does not affect the runtime PostgreSQL durability settings used by the harness.

pub fn with_tmpfs_size_bytes(self, size_bytes: u64) -> Result<Self>

Sets the maximum number of bytes available to the owned container’s tmpfs-backed PostgreSQL storage.

pub const fn without_tmpfs(self) -> Self

Uses the image’s normal storage instead of adding a tmpfs mount.

This is the compatibility opt-out for daemons that do not support tmpfs mounts and for workloads that may exceed a safe memory-backed storage limit.

pub const fn initdb_no_sync(&self) -> bool

Reports whether the profile requests initdb --no-sync.

pub const fn tmpfs_size_bytes(&self) -> Option<u64>

Reports the tmpfs size cap, or None when image-default storage is selected.
