Struct StatFs 

pub struct StatFs {
    pub total_bytes: u64,
    pub used_bytes: u64,
    pub available_bytes: u64,
    pub total_inodes: u64,
    pub used_inodes: u64,
    pub available_inodes: u64,
    pub block_size: u64,
    pub max_name_len: u64,
}

Filesystem-level statistics.

Returned by FsStats::statfs. Contains information about the filesystem’s capacity, usage, and limits — similar to the POSIX statvfs system call.

Fields

Field	Type	Description
total_bytes	u64	Total capacity (0 = unlimited)
used_bytes	u64	Currently used space
available_bytes	u64	Space available for new data
total_inodes	u64	Maximum files/directories (0 = unlimited)
used_inodes	u64	Currently allocated inodes
available_inodes	u64	Inodes available for new entries
block_size	u64	Filesystem block size in bytes
max_name_len	u64	Maximum filename length

Example

use anyfs_backend::StatFs;

let stats = StatFs {
    total_bytes: 1_000_000_000,        // 1 GB
    used_bytes: 250_000_000,           // 250 MB used
    available_bytes: 750_000_000,      // 750 MB free
    total_inodes: 100_000,
    used_inodes: 1_234,
    available_inodes: 98_766,
    block_size: 4096,
    max_name_len: 255,
};

let usage_percent = (stats.used_bytes as f64 / stats.total_bytes as f64) * 100.0;
println!("Disk usage: {:.1}%", usage_percent);  // "Disk usage: 25.0%"

Unlimited Filesystems

For backends without fixed limits (e.g., cloud storage), set capacity fields to 0:

use anyfs_backend::StatFs;

let unlimited = StatFs {
    total_bytes: 0,      // No limit
    total_inodes: 0,     // No limit
    ..Default::default()
};

Fields

total_bytes: u64

Total size in bytes (0 = unlimited).

used_bytes: u64

Currently used bytes.

available_bytes: u64

Available bytes for use.

total_inodes: u64

Total number of inodes (0 = unlimited).

used_inodes: u64

Number of used inodes.

available_inodes: u64

Number of available inodes.

block_size: u64

Block size in bytes.

max_name_len: u64

Maximum filename length.
