[jira] [Updated] (ARROW-8829) [Rust] Implement SQL parser

     [ https://issues.apache.org/jira/browse/ARROW-8829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andy Grove updated ARROW-8829:
------------------------------
    Description: 
Implement SQL parser that can take a Vec<SQLToken> and produce a SQL AST.

We can potentially break this down into separate JIRAs.

It needs to support:
 * Single table SELECT ... FROM
 * WHERE
 * GROUP BY
 * ORDER BY
 * LIMIT

It needs to support the following expressions:
 * Literals (long, string, double)
 * Identifiers
 * Binary expressions
 ** Arithmetic (+, -, *, /, %)
 ** Boolean (AND, OR)
 ** Comparison (=, !=, <, <=, >, >=, <>)
 * Unary boolean expression: NOT
 * CAST(expr AS type)
 * Aliased expressions: expr AS alias
 * Scalar functions
 * Aggregate functions
