pub fn separator(self, sep: impl Into<String>) -> Self

Set the separator between sections (default: double newline).

pub fn section( self, name: impl Into<String>, content: impl Into<String>, ) -> Self

Add a named section. If a section with this name exists, replace it.

pub fn section_with_priority( self, name: impl Into<String>, content: impl Into<String>, priority: i32, ) -> Self

Add a section with explicit priority (higher = earlier in output).

pub fn disable(self, name: &str) -> Self

Disable a section by name (it will be omitted from build output).

pub fn enable(self, name: &str) -> Self

Re-enable a previously disabled section.

pub fn remove(self, name: &str) -> Self

Remove a section entirely.

pub fn get(&self, name: &str) -> Option<&str>

Get content of a section by name.

pub fn section_names(&self) -> Vec<&str>

Names of all sections (in render order, enabled and disabled).

pub fn enabled_count(&self) -> usize

Count of enabled sections.

pub fn build(&self) -> String

Render the prompt: enabled sections sorted by priority desc, then insertion order.

pub fn has(&self, name: &str) -> bool

Check if a section with the given name exists.

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

All duplicate section names (should be empty in normal use).
