Summary:
Text is a reference-counted shared String.
It's similar to Bytes but works for utf-8 strings.
The motivation is to replace configparser's use of Bytes to Text.

Summary:
This makes the API easier to use.
Practically this makes it easier for configparser to migrate to minibytes.

Summary:
This crate provides the core features of the commonly known `Bytes` crate:
zero-copy slicing and cloning, while also supports mmap-backed buffers.
The main motivation is to replace `Mmap` in `indexedlog`. That has multiple
benefits:
- Handles 0-sized mmap more cleanly.
- Handles clones more cleanly.
- Gain the flexibility to zero-copy data without lifetime / reference.
- Gain the flexibility to switch to non-mmap data.
The `bytes::Bytes` crate does not yet support mmap buffers as of its latest
release (0.5.4).
Implementation wise, `minibytes::Bytes` uses `Option<Arc<dyn Trait>>` for the
"trait object". This makes implementing the mmap storage just one line.
`bytes 0.5.4` re-invents the "trait object" manually using unsafe code. It requires
about 50 lines to implement the mmap storage (in D19756122).
