|

//
|

// For examples, look at the `render_*` methods in the `Table` object in the
|
||||
// details view:
|
||||
//
|
||||
// - `render_blocks`, `inode`, and `links` will always return a
|

// one-string-long TextCell;
|

// - `render_size` will return one or two strings in a TextCell, depending on

// the size and whether one is present;

// - `render_permissions` will return ten or eleven strings;

// five strings.

//
|

// In none of these cases are we dealing with a *truly variable* number of

// strings: it is only when the strings are concatenated together do we need a
|
||||
// growable, heap-allocated buffer.
|

//
|

// So it would be nice to abstract the `TextCell` type so instead of a `Vec`,

//! Tree structures, such as `├──` or `└──`, used in a tree view.
|
||||
//!
|
||||
//! ## Constructing Tree Views
|
||||
//!
|
||||
//! When using the `--tree` argument, instead of a vector of cells, each row
|
||||
//! has a `depth` field that indicates how far deep in the tree it is: the top
|
||||
//! level has depth 0, its children have depth 1, and *their* children have
|
||||
//! depth 2, and so on.
|
||||
//!
|
||||
//! On top of this, it also has a `last` field that specifies whether this is
|
||||
//! the last row of this particular consecutive set of rows. This doesn’t
|
||||
//! affect the file’s information; it’s just used to display a different set of
|
||||
//! Unicode tree characters! The resulting table looks like this:
|
||||
//!
|
||||
//! ┌───────┬───────┬───────────────────────┐
|
||||
//! │ Depth │ Last │ Output │
|
||||
//! ├───────┼───────┼───────────────────────┤
|
||||
//! │ 0 │ │ documents │
|
||||
//! │ 1 │ false │ ├── this_file.txt │
|
||||
//! │ 1 │ false │ ├── that_file.txt │
|
||||
//! │ 1 │ false │ ├── features │
|
||||
//! │ 2 │ false │ │ ├── feature_1.rs │
|
||||
//! │ 2 │ false │ │ ├── feature_2.rs │
|
||||
//! │ 2 │ true │ │ └── feature_3.rs │
|
||||
//! │ 1 │ true │ └── pictures │
|
||||
//! │ 2 │ false │ ├── garden.jpg │
|
||||
//! │ 2 │ false │ ├── flowers.jpg │
|
||||
//! │ 2 │ false │ ├── library.png │
|
||||
//! │ 2 │ true │ └── space.tiff │
|
||||
//! └───────┴───────┴───────────────────────┘
|
||||
//!
|
||||
//! Creating the table like this means that each file has to be tested to see
|
||||
//! if it’s the last one in the group. This is usually done by putting all the
|
||||
//! files in a vector beforehand, getting its length, then comparing the index
|
||||
//! of each file to see if it’s the last one. (As some files may not be
|
||||
//! successfully `stat`ted, we don’t know how many files are going to exist in
|
||||
//! each directory)
