Struct ServicesViewMut 

pub struct ServicesViewMut<'a> { /* private fields */ }

Mutable view: same reads plus add/remove/replace.

Implementations

impl<'a> ServicesViewMut<'a>

pub fn new(node: &'a mut Node) -> Self

pub fn service_types(&self) -> Vec<String>

pub fn has_service(&self, type_sym: &str) -> bool

pub fn add_service( &mut self, type_sym: &str, config_source: Option<&str>, ) -> Result<(), Error>

Builds (service <sym>) or (service <sym> <config>) and adds it to the blessed shape. A bare base symbol is rewritten to (append (list (service <sym>)) <base>); cons promotes to cons*.

pub fn remove_service(&mut self, type_sym: &str) -> Result<(), Error>

Removes the element with attached leading trivia. A cons/cons* left with only its tail collapses to (cons* <tail>) (single-arg cons* is identity; a one-arg cons would be invalid Scheme).

pub fn replace_service_type(&mut self, old: &str, new: &str) -> bool

Swaps just the type symbol; a config argument is preserved.
