v1.0.0

New Features

• Extended unit coverage: added TiB, PiB, EiB, TB, PB, EB unit types.
• Display implementations for all types (e.g., format!("{}", MiB::from(5)) → "5 MiB").
• Default for all types — defaults to zero.
• Hash derived on Rounding.
• From for u64 on all unit types to extract the raw count.
• Clone, PartialEq, Eq derived on MemConvError.
• #[must_use] on all memory unit types.

Improvements

• MemorySize trait is sealed — prevents external implementations.
• Bytes::to_bytes() is a no-op — returns Ok(self) directly, avoiding a redundant multiply-by-1.
• Full documentation — crate-level docs, #![warn(missing_docs)], doc-tests, and all public items documented.
• Cargo.toml metadata — added keywords and categories for crates.io discoverability.

Breaking Changes

• From for Bytes replaced with TryFrom — converting a unit to Bytes now returns Result<Bytes, MemConvError> instead of panicking on overflow.
• to_exact() returns Result instead of Option — returns Err(MemConvError::Inexact) instead of None.
• units() renamed to count() — applies to all types.
• as_f64() renamed to to_f64() — follows Rust naming conventions.
• from_units() removed — use From instead (e.g., MiB::from(5)).
• Serde is now opt-in — enable with features = ["serde"] in your Cargo.toml.
• New error variant MemConvError::Inexact — replaces the overloaded use of Overflow for non-divisible conversions. ZeroNotAllowed variant removed.

v0.1.0

First release!

Type-safe memory size newtypes for Rust with checked conversions and arithmetic.

Stop mixing up bytes and mebibytes, or accidentally passing a decimal gigabyte where a binary one was expected.
memsizes gives each unit its own type so the compiler catches the mistakes for you.
