Struct OpenOptions 

pub struct OpenOptions {
    pub batch_size: usize,
    pub follow_symlinks: bool,
    pub one_filesystem: bool,
    pub hidden: Option<Arc<HiddenPolicy>>,
    pub exclude_special: bool,
    pub types: Option<Arc<TypeRegistry>>,
    pub budget: DiscoveryBudget,
    pub observation: Option<WatchConfig>,
    pub journal_capacity_bytes: usize,
    pub control_limits: ControlLimits,
}

Configuration for a long-lived OpenedIndex.

Scope and execution settings are flat here because each is one independent decision; display depth is absent by design and belongs to a read request. The options bind progressive discovery, exact-history bounds, and optional live observation without changing the one-shot API.

Fields

batch_size: usize

Ops per committed discovery batch.

follow_symlinks: bool

Follow directory symlinks when the configured platform semantics support it.

one_filesystem: bool

Stay on the filesystem containing the opened root.

hidden: Option<Arc<HiddenPolicy>>

Hidden-component admission, or None to retain every component.

exclude_special: bool

Exclude objects other than files, directories, and symlinks.

types: Option<Arc<TypeRegistry>>

File-type rules, or None for the rules compiled into fdu.

budget: DiscoveryBudget

Resource policy for the cold progressive walk.

observation: Option<WatchConfig>

Optional filesystem observation captured before cold discovery begins.

journal_capacity_bytes: usize

Approximate bytes the exact commit journal may retain, as crate::Commit::retained_cost estimates them; see crate::DEFAULT_JOURNAL_CAPACITY_BYTES for the default and why there is no unbounded setting. OpenedIndex::open refuses a budget below crate::MIN_JOURNAL_CAPACITY_BYTES with Error::JournalCapacityTooSmall.

control_limits: ControlLimits

The budget and the line limit .gitignore files are applied under. See ScanConfig::control_limits: a refused file ends nothing, and crate::ReadDiagnostics::controls names it and the limit that fired.

Implementations
