Struct Rules

Source
pub struct Rules { /* private fields */ }
Expand description

Struct which holds the rules for restrictions. For more information, see Ruleset.

Example

let rules = Rules::new()
    .add_read_only("/usr")
    .add_read_only("/etc")
    .add_read_only("/dev")
    .add_read_only("/bin")
    .add_read_write("/tmp/foo")
    .add_bind_port(5050)
    .add_connect_port(80)
    .add_connect_port(443);

Implementations§

Source§

impl Rules

Source

pub fn new() -> Self

Create a new Rules with no permissions

Source

pub fn add_read_only(self, p: impl Into<PathBuf>) -> Self

Add a read-only path to the rules

Source

pub fn add_read_write(self, p: impl Into<PathBuf>) -> Self

Add a read/write path to the rules

Source

pub fn add_write_only(self, p: impl Into<PathBuf>) -> Self

Add a write-only path to the rules

Source

pub fn add_connect_port(self, p: u16) -> Self

Add a port to which the command can connect port to the rules

Source

pub fn add_bind_port(self, p: u16) -> Self

Add a port to which the command can bind to the rules

Source

pub fn restrict(&self) -> Result<(), Error>

Restrict the current thread using these rules

To restrict a command’s execution, see CommandExt::restrict
