Struct SetAttrsOp 

pub struct SetAttrsOp<T> { /* private fields */ }

One attribute update for a path or opened object.

Paths can be supplied directly. Use super::Target for handles or mixed path/handle batches. Unspecified fields are unchanged; construction performs no I/O. Final symlinks are followed by default.

Implementations

impl<T> SetAttrsOp<T>

pub fn new(target: T) -> SetAttrsOp<T>

Prepare an update, following the final symlink for path targets.

pub fn with_follow_final_symlink(self, follow: bool) -> SetAttrsOp<T>

Follow the final path symlink when true, or modify the link itself when false. Opened objects retain their identity regardless of this setting.

pub fn target(&self) -> &T

The path or opened-object operand.

pub fn permissions(self, permissions: Permissions) -> SetAttrsOp<T>

Change permissions, leaving other unspecified attributes unchanged.

pub fn uid(self, uid: u32) -> SetAttrsOp<T>

Change the owner. u32::MAX is reserved and rejected before dispatch.

pub fn gid(self, gid: u32) -> SetAttrsOp<T>

Change the group. u32::MAX is reserved and rejected before dispatch.

pub fn len(self, len: u64) -> SetAttrsOp<T>

Truncate or extend the file. Zero explicitly truncates it to an empty file.

pub fn accessed(self, accessed: SystemTime) -> SetAttrsOp<T>

Set the access timestamp.

pub fn modified(self, modified: SystemTime) -> SetAttrsOp<T>

Set the modification timestamp.

pub fn with_target<U>(&self, target: U) -> SetAttrsOp<U>

Reuse all requested changes and the symlink policy with another target. This constructs an operation without I/O or cloning the original target.

pub fn requested_permissions(&self) -> Option<Permissions>

Requested permission change, or None to leave permissions unchanged.

pub fn requested_uid(&self) -> Option<u32>

Requested owner change, or None to leave the owner unchanged.

pub fn requested_gid(&self) -> Option<u32>

Requested group change, or None to leave the group unchanged.

pub fn requested_len(&self) -> Option<u64>

Requested length, including zero, or None to leave the length unchanged.

pub fn requested_accessed(&self) -> Option<SystemTime>

Requested access timestamp, or None to leave it unchanged.

pub fn requested_modified(&self) -> Option<SystemTime>

Requested modification timestamp, or None to leave it unchanged.

pub fn follow_final_symlink(&self) -> bool

Whether the final path symlink is followed.

impl<'a, F> SetAttrsOp<Target<'a, F>>

pub fn file(file: &'a F) -> SetAttrsOp<Target<'a, F>>

Prepare an update for an opened object without borrowing its pathname. The handle remains owned by the caller and is checked at dispatch.

use vfsi_core::api::{SetAttrsOp, Vfsi};
fs.vsetattrs(&[SetAttrsOp::file(file).len(1024)])?;
