[−][src]Attribute Macro smol_potat::main
#[main]
Enables an async main function.
Examples
Dynamic threads
By default, this spawns as many threads as is in the SMOL_THREADS
environment variable, or 1
if it is not specified.
ⓘThis example is not tested
#[smol_potat::main] async fn main() -> std::io::Result<()> { Ok(()) }
Automatic Threadpool
Alternatively, smol_potat::main
can used to automatically
set the number of threads by adding the auto
feature (off
by default).
ⓘThis example is not tested
#[smol_potat::main] // with 'auto' feature enabled async fn main() -> std::io::Result<()> { Ok(()) }
Manually Configure Threads
To manually set the number of threads, add this to the attribute:
ⓘThis example is not tested
#[smol_potat::main(threads=3)] async fn main() -> std::io::Result<()> { Ok(()) }
Set the crate root
By default smol-potat
will use ::smol_potat
as its crate root, but you can override this
with the crate
option:
ⓘThis example is not tested
use smol_potat as other_smol_potat; #[smol_potat::main(crate = "other_smol_potat")] async fn main() -> std::io::Result<()> { Ok(()) }
