Qty

tor_memquota::internal_prelude

Struct Qty

pub(crate) struct Qty(pub usize);

Expand description

Quantity of memory used, measured in bytes.

Like usize but FromStr and Displays in a more friendly and less precise way

Parses from (with or without the internal space):

<amount> (implicitly, bytes)
<amount> B
<amount> KiB/MiB/GiB/TiB (binary, 1024-based units)
<amount> KB/MB/GB/TB (decimal, 1000-based units)

Displays to approximately 3 significant figures, preferring binary (1024-based) multipliers. (There is no facility for adjusting the format.)

Tuple Fields§

Implementations§

impl ByteQty

pub const MAX: ByteQty

Maximum for the type

pub const fn as_usize(self) -> usize

Return the value as a plain number, a usize

Provided so call sites don’t need to write an opaque .0 everywhere, even though that would be fine.
