Struct FileDetails 

pub struct FileDetails {
    pub size: u64,
    pub modified: Option<i64>,
    pub mode: Option<u32>,
    pub readonly: bool,
}

What one entry is besides its name: its size, when it changed last, and its permissions.

A symbolic link is read as itself rather than as what it points at, the way the rows show it: a link out of the folder must not be followed for a number on screen.

Fields

size: u64

Its size in bytes. A folder’s own size says how big the folder itself is on disk, not what is in it; adding up a folder means reading all of it, which a manager never does by itself.

modified: Option<i64>

When it changed last, in seconds since 1970-01-01 UTC, or None where the system does not say.

mode: Option<u32>

The permission bits, where the platform has them (unix), and None where it does not.

readonly: bool

Whether it may not be written, which every platform says.

Implementations

impl FileDetails

pub fn read(path: &Path) -> Option<Self>

Reads the details of the entry at path, or None when the system says nothing about it — it is gone, or may not be looked at.

This touches the disk, so it belongs on a background thread; FileManagerState asks for it with Command::perform and never while drawing.

pub fn size_text(&self, folder: bool) -> String

The size in the largest unit that leaves a number worth reading: 840 B, 9.4 kB, 12 MB. A folder’s size is left out, because its own size says nothing about what is in it and a number that means nothing is worse than none.

pub fn modified_text(&self) -> String

When it changed last, as the year, the month, the day and the clock the machine stands by: 2026-09-20 14:32. Empty where the system does not say.

pub fn permissions_text(&self, folder: bool) -> String

Who may do what with it: the nine letters unix writes them with (rwxr-xr-x), and on a platform without them the one thing it does say, whether the entry may be written.
