Struct CatalogFile 

pub struct CatalogFile {
    pub statements: Vec<String>,
    pub settings: BTreeMap<String, String>,
}

The contents of a catalog file.

Fields

statements: Vec<String>

settings: BTreeMap<String, String>

Settings the database keeps, by their full name (ursa.index_storage_limit), as SET would take them.

Implementations

impl CatalogFile

pub fn parse(text: &str, name: &str) -> Result<Self>

Parse a catalog file’s text. name is how messages name the database.

pub fn read(path: &Path, name: &str) -> Result<Self>

Read and parse the catalog file at path.

pub fn to_text(&self) -> String

The file’s text: format, version, then one statement per line, then the settings if there are any, one per line, with a trailing newline.

pub fn write(&self, path: &Path, scratch_dir: &Path, name: &str) -> Result<()>

Write the file at path atomically: write a temporary file in scratch_dir (on the same filesystem), fsync it, rename it over path, then fsync the directory.
