Provided methods

fn display<'a>(&'a self, db: &'a dyn HirDatabase) -> HirDisplayWrapper<'a, Self> where
    Self: Sized, 

Returns a Displayable type that is human-readable. Use this for showing types to the user (e.g. diagnostics)

fn display_truncated<'a>(
    &'a self,
    db: &'a dyn HirDatabase,
    max_size: Option<usize>
) -> HirDisplayWrapper<'a, Self> where
    Self: Sized, 

Returns a Displayable type that is human-readable and tries to be succinct. Use this for showing types to the user where space is constrained (e.g. doc popups)

fn display_source_code<'a>(
    &'a self,
    db: &'a dyn HirDatabase,
    module_id: ModuleId
) -> Result<String, DisplaySourceCodeError>

Returns a String representation of self that can be inserted into the given module. Use this when generating code (e.g. assists)
