Struct FileLayout 

pub struct FileLayout {
    pub name: String,
    pub extent: Extent,
    pub file_type: FileType,
    pub timestamps: Timestamps,
    pub attributes: u32,
    pub symlink_target: Option<String>,
}

File layout with pre-calculated extent (for metadata-only writing).

This structure describes where a file’s data is located on disk without containing the actual data. Used for operations that only need to write/update filesystem metadata.

Fields

name: String

File name (without path).

extent: Extent

Location and size of file data on disk.

file_type: FileType

Type of the file entry.

timestamps: Timestamps

File timestamps.

attributes: u32

Filesystem-specific attribute flags.

symlink_target: Option<String>

Optional symlink target (only valid if file_type is Symlink).

Implementations

impl FileLayout

pub fn new(name: impl Into<String>, extent: Extent) -> Self

Creates a new file layout.

pub fn with_type(self, file_type: FileType) -> Self

Sets the file type.

pub fn with_timestamps(self, timestamps: Timestamps) -> Self

Sets the timestamps.

pub fn with_attributes(self, attributes: u32) -> Self

Sets the attributes.

pub fn with_symlink_target(self, target: impl Into<String>) -> Self

Sets the symlink target (only meaningful for symlinks).

pub fn size(&self) -> u64

Returns the file size in bytes.

Trait Implementations
