Struct CollectionOptions 

pub struct CollectionOptions { /* private fields */ }

Supported options for creating or opening a collection.

Storage layout, buffer, and segment knobs remain outside the public contract:

use a3s_vec::CollectionOptions;

let mut options = CollectionOptions::new().unwrap();
options.set_max_buffer_size(1024).unwrap();
options.set_segment_num(2).unwrap();

Implementations

impl CollectionOptions

pub fn new() -> Result<Self>

pub fn set_read_only(&mut self, read_only: bool) -> Result<()>

pub fn read_only(&self) -> bool

pub fn set_durability(&mut self, value: Durability) -> Result<()>

pub fn durability(&self) -> Option<Durability>

pub fn set_io_backend(&mut self, value: IoBackend) -> Result<()>

Overrides the process-wide derived-sidecar I/O backend for this handle.

When absent, the backend configured through crate::ConfigBuilder is captured when the collection is created or opened.

pub fn io_backend(&self) -> Option<IoBackend>

Returns this handle’s explicit I/O backend override, if any.

pub fn set_resource_limits( &mut self, value: CollectionResourceLimits, ) -> Result<()>

Applies a typed collection-local resource policy.

pub fn resource_limits(&self) -> CollectionResourceLimits

Returns the resource policy that this handle will capture.

pub fn set_storage_ceilings(&mut self, value: StorageCeilings) -> Result<()>

Overrides process-wide persistence DoS ceilings for this handle.

When absent, the ceilings configured through crate::ConfigBuilder (or product defaults) are captured at create/open. Values are never inferred from host RAM or free disk.

pub fn storage_ceilings(&self) -> Option<StorageCeilings>

Returns this handle’s explicit storage-ceiling override, if any.

Trait Implementations

impl Clone for CollectionOptions

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for CollectionOptions

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

Formats the value using the given formatter.

impl Default for CollectionOptions

fn default() -> Self

Returns the “default value” for a type.
