pub struct DbError { /* private fields */ }
Expand description

A Postgres error or notice.

Implementations§

source§

impl DbError

source

pub fn severity(&self) -> &str

The field contents are ERROR, FATAL, or PANIC (in an error message), or WARNING, NOTICE, DEBUG, INFO, or LOG (in a notice message), or a localized translation of one of these.

source

pub fn parsed_severity(&self) -> Option<Severity>

A parsed, nonlocalized version of severity. (PostgreSQL 9.6+)

source

pub fn code(&self) -> &SqlState

The SQLSTATE code for the error.

source

pub fn message(&self) -> &str

The primary human-readable error message.

This should be accurate but terse (typically one line).

source

pub fn detail(&self) -> Option<&str>

An optional secondary error message carrying more detail about the problem.

Might run to multiple lines.

source

pub fn hint(&self) -> Option<&str>

An optional suggestion what to do about the problem.

This is intended to differ from detail in that it offers advice (potentially inappropriate) rather than hard facts. Might run to multiple lines.

source

pub fn position(&self) -> Option<&ErrorPosition>

An optional error cursor position into either the original query string or an internally generated query.

source

pub fn where_(&self) -> Option<&str>

An indication of the context in which the error occurred.

Presently this includes a call stack traceback of active procedural language functions and internally-generated queries. The trace is one entry per line, most recent first.

source

pub fn schema(&self) -> Option<&str>

If the error was associated with a specific database object, the name of the schema containing that object, if any. (PostgreSQL 9.3+)

source

pub fn table(&self) -> Option<&str>

If the error was associated with a specific table, the name of the table. (Refer to the schema name field for the name of the table’s schema.) (PostgreSQL 9.3+)

source

pub fn column(&self) -> Option<&str>

If the error was associated with a specific table column, the name of the column.

(Refer to the schema and table name fields to identify the table.) (PostgreSQL 9.3+)

source

pub fn datatype(&self) -> Option<&str>

If the error was associated with a specific data type, the name of the data type. (Refer to the schema name field for the name of the data type’s schema.) (PostgreSQL 9.3+)

source

pub fn constraint(&self) -> Option<&str>

If the error was associated with a specific constraint, the name of the constraint.

Refer to fields listed above for the associated table or domain. (For this purpose, indexes are treated as constraints, even if they weren’t created with constraint syntax.) (PostgreSQL 9.3+)

source

pub fn file(&self) -> Option<&str>

The file name of the source-code location where the error was reported.

source

pub fn line(&self) -> Option<u32>

The line number of the source-code location where the error was reported.

source

pub fn routine(&self) -> Option<&str>

The name of the source-code routine reporting the error.
