Struct BalanceArgs 

pub struct BalanceArgs { /* private fields */ }

Per-type filter arguments for a balance operation, corresponding to btrfs_balance_args.

Construct one with BalanceArgs::new and chain the setter methods to enable filters. Each setter automatically sets the corresponding flag bit.

Implementations

impl BalanceArgs

pub fn new() -> Self

Create a new BalanceArgs with no filters enabled.

pub fn profiles(self, profiles: u64) -> Self

Filter by chunk profile bitmask. The value is a bitmask of BTRFS_BLOCK_GROUP_* profile flags.

pub fn usage(self, percent: u64) -> Self

Filter chunks whose usage is below percent (0..100).

pub fn usage_range(self, min: u32, max: u32) -> Self

Filter chunks whose usage falls in min..=max percent.

pub fn devid(self, devid: u64) -> Self

Filter chunks that reside on the given device ID.

pub fn drange(self, start: u64, end: u64) -> Self

Filter chunks whose physical range on-disk overlaps start..end.

pub fn vrange(self, start: u64, end: u64) -> Self

Filter chunks whose virtual address range overlaps start..end.

pub fn limit(self, limit: u64) -> Self

Process at most limit chunks.

pub fn limit_range(self, min: u32, max: u32) -> Self

Process between min and max chunks.

pub fn stripes_range(self, min: u32, max: u32) -> Self

Filter chunks that span between min and max stripes.

pub fn convert(self, profile: u64) -> Self

Convert balanced chunks to the given profile.

pub fn soft(self) -> Self

When converting, skip chunks already on the target profile.
