Implementations

impl RawPSpawnConfig

pub const fn new_from_raw( name: OptZero<Str>, argv: OptZero<Slice<Str>>, env: OptZero<Slice<Slice<u8>>>, flags: SpawnFlags, stdio: OptZero<FFINonNull<ProcessStdio>>, priority: RawContextPriority, custom_stack_size: OptZero<ShouldNotBeZero<usize>>, ) -> Self

Creates a new process spawn configuration with the latest revision from raw FFI values

pub unsafe fn new<'a>( name: Option<&'a str>, argv: Option<&'a mut [*mut str]>, envv: Option<&'a mut [*mut [u8]]>, flags: SpawnFlags, stdio: Option<&'a ProcessStdio>, priority: RawContextPriority, custom_stack_size: Option<NonZero<usize>>, ) -> Self

Construct a new process spawn configuration from the given rust parameters.

Safety

The given parameters must live as long as the returned value is alive, because currently this doesn’t have any lifetime bounds.

argv and envv may be reused to store their FFI representations, even though nothing should change because the layout matches the rust representation, it is still not exactly guaranteed but this should be resolved through this RFC
